Is something wrong with me for giving up on love?

I have been hurt so many times over the last few years by people that I have gotten used to being hurt by people. I will be anyone's closest friend and guard their most precious secrets. I am loyal to the very end. In return, I have received betrayal and lies and humiliation. I used to ask girls out on a date; now, I have no drive to do so anymore because of past relationship and friendship hurts. I even had a girl basically ask me out and show interest, and I turned her down nicely to stay her friend. What is wrong with me?
