While I agree with what people have said about it not being your fault and that you are being abused, I also understand that it is not so easy to just leave, even if that seems the best for you in the long run. And it might be true. I was in a situation with a partner who became physically and also emotionally abusive. I left, moved out, and took a break. It turned out that some of what was causing the problem was medication he was taking that when I insisted that he see someone and get evaluated, he was pulled off of them and eventually we restored our relationship. There is no abuse any more, nothing close. I never thought it was possible when I left, but it ended up working out after all. I had to do lots of extra therapy during the period and had to deal with people taking sides during the separation and lost some close friends. But I survived.

I'm not saying this is a blueprint at all. What I'm trying to say is that I understand the difficulty of the situation and that leaving it is not easy. And in my case, it turned out to be okay in the long run, but the relationship was a very long one and what was happening stood out as unusual so I had a feeling that something was up and it turned out that I was right. I still am sensitive to this and make my boundaries clear if there is anything even slightly off. This takes a lot of work and strength. I couldn't have done it without a therapist supporting me, both in my decision to be free of abuse and independent and then my very careful and cautious attempt to work it out. Again I'm not giving advice or saying my experience is to be followed at all. I'm just trying to express that it can be complicated and difficult and not as straightforward. There is such a thing as a cycle of abuse that drives some relationships. If that turns out to be true for yours, then getting out would be the best thing. And getting out for now also seems like a good thing to do. You can't really see it when you are so involved up close. You need some separation and distant to know what you really feel apart from this relationship and what would be best for you.
