A broken relationship?

We have been together for a year now, within this time many events have accured that have hurt me whilst being with him. At the start, we were seeing eachother and he did the sly job of texting other girls to meet up. I did not know this til later on when we got more serious, he appoligised and we moved on together and got closer. But he covered up the fact he got hooked up with another chick! His loyalty to me is near nothing and the way he speaks to me is awful, his even humiliated me about how i'm "bad" in bed when he was fuming with him but when we are great, its amazing we have so much fun together and we feel so strong. Im 7 weeks pregnant with his child and now have considered to separate from him, he has no problems being there for our baby but I think its time to part ways as being a couple. I cant take having someone have low respect for me even though he says he "loves" me. What are your thoughts?
