Despite what rom-coms might lead you to believe, being single is not the worst. In fact, some people may even (gasp!) prefer the single life over being coupled up. Just think about it: When you're single, you don't have to answer to anyone. You can hang out with whoever you want, vacation wherever you want, and watch whatever you want on TV. Whether your current status is dating without commitment or 100% single lady, there are some Myers-Briggs personality types who are single most of the time and like it that way. You do you, girl.
If you're consistently single and wondering why, it may just be that your personality is better suited for the single life. That doesn't mean you'll never find yourself a partner if you decide you want one, of course. It just means that you like to make your own rules and do things your own way, and that's A-OK. The right person will likely understand that and give you the freedom that you thrive on. Not sure what your personality type is? Take the test to find out. There may be a reason why being single sounds way more fun to you than being in a relationship.
