If you're really, really falling in love, you probably already know it... because falling in love feels a little bit like you're on the verge of vomiting.
Still, if there's any doubt in your mind that you're really in-it-to-win-it, there are certain telltale behaviors that can prove it, specific to your astrological sign.
Here how to tell you're DEFINITELY in love, based on your zodiac sign.
Aries: You want to fight/fuck them at the same time.
Aries is the youngest sign in the zodiac, and, in many ways, people under this sign act like toddlers when they're overwhelmed with feelings.
They're ruled by the planet Mars, which is also the planet of masculine energy, so when an Aries starts getting those lovin' feelings, they don't know what to do other than act on them sexually.
If they can't get what they want, they'll throw a tantrum, hoping ultimately that this will lead to sex. That's because Aries fall in love the same way they do everything else... impulsively.
They're extremely physical, enthusiastic and driven lovers, prone to temper tantrums one moment and declarations of undying love the next.
...Like I said, they're the babies of the zodiac. Expect the unexpected.
Taurus: You want to show them off to everyone you know.
Taurus is ruled by the planet Venus, which is the planet of love and money, and they love to show off.
While they aren't particularly jealous, they can be somewhat possessive over their things, and they do believe loved ones "belong" to them.
If you're dating a Taurus and they bring you out to meet their friends and family, they're not only making an effort to get closer to you, they're also making a statement that you are theirs.
And they intend to show you off so that everybody knows it.
Gemini: You aren't bored with them.
Gemini is a sign ruled by the planet of communication and technology, Mercury.
Geminis are the great communicators of the zodiac, and their gift for gab really shines brightly when they're in love. They'll text all day, sharing articles, pieces of information, photos they've taken and random ideas they have.
A Gemini's partner might wonder whether they're actually cared for or if the Gemini just likes to talk, but the answer is a resounding "Yes" to both questions.
The real test of whether or not a Gemini has fallen for someone is simply whether or not the person can hold the Gemini's attention.
Cancer: You want to literally smother them with love.
Cancers are ruled by the Moon, a locus of feminine energy, associated with the mother and the home.
When Cancers truly start to fall for someone, they are taken over by a deep desire to nourish that person in the same way that a mother would want to nourish her child.
By cooking for your lover, preparing their meals and intuiting their every need, you feel as though you're giving them the kind of love you would want for yourself.
Because of how deeply emotional you are, Cancer, you want to surround your lover and protect them with the full force of your feelings.
Be careful not to suffocate your partner, though. Not everyone desires the kind of care-taking in relationships that you do.
Leo: You want to spend money on them.
When a Leo falls in love, they want to sing it from the mountaintops.
They don't typically fall in love easily because they value themselves so highly that they honestly find it difficult to find partners who are good enough for them.
When they do fall in love, however, they fall fast and hard, and have no trouble letting the person know.
Leos' natural generosity is amplified when they fall in love.
Represented by the lion, Leos consider themselves to be the kings and queens of the zodiac, so in their eyes, their lovers are the lucky "chosen ones" who will be showered with gifts, affection and warm gestures of love.
Leos spare no expense letting their loved ones know how much they are appreciated and loved, but, more importantly, how lucky they are to have been chosen as mates.
Virgo: You want run their errands.
It may seem terribly unromantic at first glance, but when Virgos fall in love, all they want is to help their lovers in everyday practical matters.
Virgos are ruled by the sixth house of service, health and personal hygiene, pets, daily routines and responsibilities.
When Virgos fall in love, they will find themselves going out of their way to assist their loved ones by walking their dog, leaving helpful reminders about doctors' appointments or work meetings, or bringing their lover a forgotten umbrella at work when it's raining.
This may not be the most romantic sign of the zodiac, but Virgos understand that "to love" someone is a verb. For Virgos, it's what you do -- not what you say -- that is most important in a relationship.
Libra: You want to create a perfectly balanced partnership.
Libra resides in the 7th house of relationships and partnerships, and Libras are ruled by the planet Venus.
It's part of a Libra's soul-mission on this earth to learn to love and live in partnership with others, as evidenced by their symbol of the scales.
Despite being the most partner-oriented sign in the zodiac, Libras tend to have many relationship crises. When a Libra falls in love, they're very keen to set the balance straight, to make sure everything is fair.
This can involve an awful lot of ups and downs and a fair amount of arguments, but it still won't stop a Libra from desperately trying to even the scales regardless.
When you're really in love, you just want the relationship to be perfect. You can't help it; it's part of your mission, part of the built-in theme of your life.
Scorpio: You want to avoid them.
There's no one more complicated when it comes to intimacy than a Scorpio, the sign associated with the 8th house of sex, death and shared resources.
When a Scorpio falls in love with someone, they take it more seriously than any other sign in the zodiac.
Because of this all-or-nothing, no-going-back attitude, a Scorpio's initial reaction to the overwhelming, all-consuming feelings of love are to avoid them entirely.
Because Scorpios view relationships as extensions of sexual intimacy, they'll only enter them when they feel their lovers can be trusted.
Once they're ready, Scorpios go in with a willingness to merge not only sexually, but to merge housing, family, bank accounts and all resources entirely, to become one.
The problem with this serious approach to partnerships is that it may lead to a Scorpio either living in isolation or entering into unemotional, "safe" relationships with stable partners.
...While keeping someone on the side with whom they experience a more passionate intimacy.
Sagittarius: You want to play with them.
Sagittarius is represented by the archer, and like the symbol of a speeding arrow, they race past others to pin down their lover, like prey.
They see love as a race to beat the competition, and once they've found their lovers, they expect them to join in on their enthusiastic, sportsman-like approach to relationships.
Because Sagittarians fear the restriction of marriage and traditional obligations, they choose partners who they feel can keep up with them.
They're always looking for the next journey, eager to see what new adventure awaits them. And they want their partners to be right there with them, to feel as though they're tag-teaming life together.
Capricorn: You want to lecture them.
Capricorns are ruled by the 10th house of social status, career and the father.
Capricorns lie opposite to Cancers on the astrological wheel, and so their approach to love is similar, only the quality of it is very different.
Capricorns approach their lovers with a stern, almost paternal guiding hand.
Being the most status-conscious sign, Capricorns consider their lovers to be extensions of their own reputation, and won't choose lovers who don't make them look good.
When Capricorns truly fall for someone, they want to protect them from any sort of criticism they might be unknowingly bringing on to themselves.
Aquarius: You'll start calling them "your best friend"!
Possibly the most independent of all astrology signs, Aquarius is the loner of the zodiac.
Aquarians have many acquaintances, but very few real friends, as they're often busier worrying about what they can do for the world than what they can do for one person.
When an Aquarius falls in love, they won't even know what's happening at first.
Aquarians will find themselves bugged by an endless curiosity about the other person: a desire to know their opinions and to want their input on everything.
After some time goes by, usually long after their partner has already intuited their feelings, they'll realize as suddenly as a light bulb going off, and will declare it as a surprising new discovery, "I think you're my best friend!"
...In Aquarian-speak, this translates to "I love you," but I'll leave that to them to discover.
Pisces: You lose your grip on reality.
Ruled by mystical Neptune, Pisces is the most romantic sign of the zodiac.
Pisceans get caught up in the fairytale of love most of all, and so the greatest sign of them falling for someone is that they lose their grasp on reality.
This is all well-and-good if they manage to use their judgment, but the trouble with Pisceans is that they don't have a lot of that when it comes to love.
This is a tough one, because the last person to notice that their lover might not be all they'd hoped for is usually a Pisces, whose friends won't want to say anything for fear of hurting their feelings.
Somehow, Pisceans never quite rid themselves of the notion that there is a special someone, a soulmate, who will go through fire and water to claim them.
If anyone can find their soulmate, a Pisces can, but they have to kiss a lot of frogs before they get there.
