emotional/psychological abuse and games

This is going to sound weird, and I hope I explain myself, so everyone can understand. I think I am in an abusive relationship. He is very punitive, and he punishes me through withholding sex, effection, and love. He never wants to have intercourse, but he wants to recieve pleasure in other ways. I think he does this, so he can control when I receive pleasure. I'm not sure though, so if anyone has experienced this please let me know. Also. he calls me all the time, and asks me what I have done for the day. He also gets real mean if I don't answer the phone or when I go somewhere and don't tell him. he says he worries about me, but I'm not sure he is telling me the truth. He also does creepy things that scare me. He bought me a stuffed animal that strips for valentines day. He does this thing where he calls me at night and asks me what me and the bear are up to and that he knows we are having an affair. He also has calls me marshmallow instead of my real name. I am ten pounds overweight, but I still look attractive, even though I'm not skinny. I think he is putting me down when he calls me marshmallow. He always says I need to loose weight. He won't let me go! I have tried to leave him, but he just persists and wears me down. He says I will never find anyone else that will put up with me. I don't understand this because I do everything to please him. Someone please help! Tweet
