I Am Single But Not Sure If I Am Ready to Mingle

I am 19 years old, nice to everyone, decent looking, good body, but I have never been in a serious relationship.. by my own choosing. Sometimes I feel like I'm messed up because I choose to be alone and I'm not doing what the crowd does but then I try to imagine myself in a relationship and remember why I don't mess with that. Why do you guys even bother? Feelings will just be hurt, hearts will be broken, betrayal is bound to happen or the flame between you two will die eventually. It's all so pointless! why would I want to put myself through more pain than I've already been in. I feel like I'm too smart for that. No one has ever been worth the risk to me.... maybe I'm too picky.
