[quote annebutnoththeanneyouknow]@Shouldbedoing i feel like he might be. But i dont think he is intentionally doing it, most of it i think is a poor choice of words[/quote]
Bejaysus, this charmer has done a number on you OP.
What is unintentional about continuing to grope you, feeling entitled to sex simply because you are still unfortunately sharing a roof, & crassly remarking that he "wants one last shot of me!"?
That's not a poor choice of words.
It deliberate harrassment.
Put a stop to it. Tell him that he is not to touch you - at all. Not sexually, not playfully, not - anything, He is no longer your partner. He does not get to touch you.
Don;t listen to any bullshit he gives you for saying this.
Just calmly say "if you grope or even touch me again I will call the police."
And mean it. He is intentionally grabbing at you without your consent, & sexually harrassing you. That is against the law. He could be hit with a restraining order, if you keep a diary of all the times & dates he is groping at you.
Hang on in there. Oh! - & YOU are not splitting up the family. You are protecting yourself & your DC from being assaulted/witnessing a sex pest in action.
