So my boyfriend was really nice and a total gentleman when we first started going out. But now it's like he is changing. He is ALWAYS making dirty jokes. The other day I asked him what he wanted to eat, and he said "you". He is always grabbing my ass and sliding his hand up my dress. The other day he did it so much that I burst into tears and told him he was a goddamn pig. It's like he is compltely obsessed with sex, it's all he ever talks about. He's not who I thought he was. Should I dump him? I feel really hurt over this, it's like he doesn't respect me at all. He has also slept with 9 girls before me. I REFUSE to sleep with him.
