Why am the only one?

I'm tired of it. It tears me up inside and threatens to take a hold of my life and squeeze it until it is no more. Why am I the only one without someone? Really. This isn't a rant about how I had love then lost it. I've NEVER had it. No one has asked me out and I'm not gonna do it for myself. I want someone to show interest in ME, not the other way around because all my crushes are silly and unrealistic, as I've been told.
I know I'm not the prettiest girl there is, but I think I've got a lot to offer, if I can be selfish for a minute. I'm unbelievably nice to EVERYONE, and I constantly ask myself, "Why am I so kind all the time, people will push me around." And they have from time to time. I hate confrontation but I love to read. Sure, I'm a bit of a geek and some people see me as the quiet, shy, smart girl. I'm trying to put myself out there, I REALLY am!
Sorry to whoever read this. I'm just a bit emotional at times and I often misread peoples' motives, for sure.
