its like he’s not even ‘acting’ he actually is. He doesn’t put on a perfect facade and then give me a ‘look’ like I’m in trouble later like you imagine a typical abuser.
Right, exactly. It really can be that simple. When people explain some of his actions around how he's keeping you controlled, or how he sets up a situation to sexually assault you, I don't think they mean to say he's some kind of evil genius. He's not consciously psychoanalysing you and developing a strategy, knowingly. He's doing these things instinctively and because, over years of abuse, he's learned what to do to get the result he wants, unconsciously. That's part of who he is. I can also quite believe another part of who he is can be helpful, non-confrontational, outwardly supportive. But when he wants sex or you aren't behaving how he wants or he's stressed or whatever other reason, he behaves abusively. That's just who he is, OP.
But can you live the rest of your life wondering which side of your husband you're going to get each day, and remain mentally and physically well?
