Getting girls to like me.?

Now Ya......Well see I am a good guy. I go to all the dances, have a date, I am tall, have a deep voice, but I can't seem to get girl to like me at all. I mean I have gotten asked out...by hoes. But I mean I want to go out with decent girls but they are all taken, or I just can't puck up the courage. What I mean is I don't have a cell phone and all girl want to do its seems now it text. So thats a factor that scares me. Also why do girls like going out with abusive losers that do nothing but talk about them behind their back? Is it true nice guys finish last in dating....oh btw I am 16 almost 17 in a month.
