Will I ever find a girl who likes me?

I'm a nice guy, I really am. I am not a "bad boy" and I'm sick of girls who expect me to be a bad boy. I love taking care of people, I love standing up for people, I love helping people, I just love people. Everytime I get "close" to a girl they are always in the friend zone... I just don't understand it, girls like me but as a friend someone they can rely on. People tell me I'm too nice, how can I be too nice? I have a backbone too, I'm not emotional I don't go and cry at movies and get all goopy and stuff in a relationship. But I am nice, I compliment people, I do nice things... I thought I was the "ideal" guy but obviously I'm not. No girl seems to think so, anyway. what am I doing wrong?
