too many feelings

Apparently, I have too many feelings how is that even possible. I can be quiet emotional at times though its not my fault, I get hurt easily. But why does he do things that will hurt me when i repeatedly have told him not too. What is love? this is such a confusing term to try and define. Can you love someone but not like them as a person? I think I loved him once, but he let me down so many times that it decreased. Since I was a child I had dreamt of the day that I would fall in love and prince charming would come and sweep me off my feet, but when he did come it wasn't romantic. He was controlling and possessive, my life had become revolved around him I had no friends, no social life nothing. I was all alone and all his. He made me do things I was uncomfortable with but I did them to keep him. Why is it that we try so hard to keep the ones we love?
