I have been with my boyfriend a little over 5 months at work. Everything started quite intense between us and I quickly gave up my home and moved in to his. Everything was great. He was loving, attentive and I never doubted his feelings for me once. Then he got bogged down with some stuff and said it was best I leave. I had no choice but to go and stay with an ex who I was still friends with as I had no friends or family close by. After a few days he told me he had made a mistake and wanted me back. I was hesitant but I came back and since then everything has gone from bad to worse.
He won't speak to me, he never wants to spend time with me. He only shows me affection when he wants something sexually and we never actually have sex, he finishes and then doesn't speak to me again. He will tell me there is some family emergency and leave me on my own. He doesn't call or text and ignores me completely. He done this recently and I found out the next day that there had been no family emergency at all.
When I try to leave he tells me he doesn't want to lose me and it usually turns in to a screaming match that he wins. I feel helpless. He says he doesn't mean to treat me like this but he can't stop himself because he has so much else going on at the moment. What does any of this mean? I am going crazy and he won't give me answers.
