My boyfriend is totally different?

I meet him last year September, we’ve been great. We moved in together in September and that’s when we started to have this conflicts. We fight almost everyday. He said few times that he wants to break up, then when we good I’m a love of his life. Then he says he don’t love me, then that he does. He had difficult childhood but I am just so sad because all the things he’s throwing on my face. Today he just bombed me. He said our sex is not good, that his ex was the only one he loved, that he’s not happy with me, that he feels empty. Yesterday we had a great time, laughing, having sex, eating dinner. I don’t know, what’s the fuck is wrong with me. What this is? I had so many bad relationships before, and when I meet him I thought his different, his good with my family, he was awesome with me before. I don’t know if I got so horrible that he started to have this hate feelings for me, or he was always like this. I think I love him, I don’t even know anymore, after hearing all this I’m literally nauseous. I also was pregnant 2 months ago, but lost it, and he was excited. I feel like his freaking bipolar or something. What do you guys think
