If someone isn't over their ex, then they might still be pretty upset about the way things ended. "They still complain about their ex and what they did or didn't do, and that carries charge: bitterness, resentment, anger or sadness," Fehr explains. "They are stuck wishing that things were different and they can't let it go."

Breakup hurts, and healing from a breakup certainly takes time. But when the person you're seeing can't make like Elsa and just let it go, they probably aren't over their ex, which means it might be time to have a conversation. After all, they’ll never be able to open themselves to you if they’re still caught up in the drama of a past love.

Everyone has a different opinion about whether or not staying friends with an ex is a good idea. To each their own, but according to Fehr, someone who maintains regular contact with an ex might be doing so because they're not ready to fully part ways. "They still stay in touch with the ex, in person or via social media, and discuss what they're doing in and with their lives," she says. "They are a presence in their mind and thoughts."

That's not to say that someone who's still friends with an ex will never be able to give you the kind of relationship you deserve. That's very much not the case. You can absolutely still be friends with an ex and be emotionally available to have a relationship with someone else. Nevertheless, you will know when that relationship is a little too close for comfort, especially if the breakup is still very fresh and the exes are regularly communicating and meeting up without you.

If your eyes have ever wandered onto your bae's phone screen, only to find that they're scrolling through their ex's Insta, they might still be hung up, as behavioral scientist and clinician Clarissa Silva tells Elite Daily. In fact, creeping on an ex’s social media at any point isn't particularly healthy. "This only stagnates their growth because it occupies their brain with thoughts about their exes’ activities and whereabouts,” she says.

It probably isn’t a big deal if your partner follows their ex on social media, but if they’re constantly checking up on it or even engaging with that person’s posts, then it’s probably time to talk. According to clinical psychologist Dr. Joshua Klapow, "The frequent reminders of the person, the tracking of their lives, keeps us from mourning the loss of the relationship. The result is being stuck in between being with them and moving forward."

This one might be hard to pick up on if you've only recently started dating this person, but if they're not over their ex, they might become distracted by thoughts of them. "Especially if someone recently ended a relationship, the person might be constantly reminded of good times together — or bad," Fehr says. "It might feel like everything is a trigger to some memory. They might bring it up or you might feel them drifting away and getting lost in the memory."

Sometimes you only have your intuition to go on, but if you notice that they're becoming more distant, they could be thinking about their ex. Avoiding making accusations (even though it’s tempting), and instead, when your SO feels far away, you could simply prod them back by asking, “What’s on your mind?” If they refuse to answer, there could be a reason.

A good sign someone is not over their ex is if they only hold their new partner to a standard based on the ex. There are always major relationship deal breakers — like not getting along with friends or family — but if your current date, for example, is annoyed that you ordered lemonade because that was their ex’s favorite or tells you, “My ex would never wear that,” then it should be considered a red flag.

Author and love coach Susan Winter previously told Elite Daily that, while “having gratitude for a positive past love affair” is totally healthy and fine, it’s not healthy for someone to compare every new person they meet to their old flame. “Carrying a torch for an ex robs us of finding love in the future," she said. "Idealizing an ex eliminates the possibility of anyone new entering our lives."

Last, but certainly not least, someone who doesn't stop talking about their ex probably isn't over them. "Their number one topic is their ex," Silva explains. "When someone is struggling to get over an ex, they often reminisce about the relationship." But, there is a difference between reminiscing fondly and reminiscing obsessively to the point where everyone needs to know every detail about their former relationship. That is never fun to sit through.

Host of the breakup BOOST podcast Trina Leckie agrees, telling Elite Daily that someone isn't over their ex "if they talk about their ex often, bring up their ex in conversation, or get emotional about their ex." Additionally, if they compare you to their ex — whether it be bedroom tactics, hobbies, or life details (i.e: "Oh! My ex went to that college too," or "My ex used to love it when I did [insert sexual act] to them.") — they probably aren't over it, Leckie adds.
