re your comment:-
"I’m not sure tho if it is abuse I must infuriate him because he very rarely gets a rise out of me. He also controls his moods around his grandparents too but not his DM she knows what he’s like. She’s witnessed his behaviour a few times".
What do you get out of this relationship now?.
What did you learn about relationships when you were growing up?
What is your definition of abuse?. Abuse is not just physical in nature, its also about power and control. This man wants absolute over you. He does not get a rise out of you always probably also because you become quiet, walk on eggshells and otherwise become subservient to him in his presence. Abuse like you describe is indeed insidious in its onset and creeps up on people. He targeted you, of that I have no doubt at all. He saw a "strong woman" to take down with him, some abusers like these types of women because it presents them with an additional challenge to take down with him. He is dragging you and in turn your kids down with him.
You are in the thick of an abusive relationship and your children are being affected by all this around them as well. What do you want to teach your children about relationships and what are they learning here?. Would you want them to have this model of a relationship you are showing them as adults?.
Abuse is not about communication or a perceived lack of, its about power and control.
What you write about him all points to him being abusive.
This man hates women, ALL OF THEM particularly his mother who left her son at that time with her grandparents.
You are not married to this man nor have financial ties to him. You can indeed get him out of your home, your children will also thank you for doing that. Get legal advice too. I would seriously consider obtaining both non molestation and occupation orders re him as well going forward.
His abuses will take you a long time, perhaps years now, to recover from and your recovery from this has not started yet. Womens Aid would be of great benefit to you now as would their Freedom Programme.
