I don't think I'll ever fall in love?

Mainly because I don't want to, I don't like meeting new people, everyone is a phony and turns out to be someone else in the end. I've been in "relationships" before..if you could call it that and I have absolutely no trust. I've seen the way married couples usually end up, completely miserable. After seeing my father verbally abuse me and my mom for practically all my life I'm a bit afraid of getting so close to someone then having them treat me like that, and I feel like any man will do this to me just because I'm so accustomed to being around it. And the funny thing is he showed no sign of this behavior for the first 2 years of him and my mom dating. I don't like letting my guard down and obviously that is something you have to do when you're in love. Also my mom cheated on my dad because of this behavior and that is something I'm afraid of as well, being cheated on because it completely destroyed my dad. I feel like any man would cheat on their significant other at least once. I don't want to feel that kind of pain so I'd rather be alone forever. Does anyone feel this way? I hope I'm not alone.
