Rapped by husband and much more.. help

[Fall3]

Start with a bit of a background I've been married to him for 5 year and we have 3 kids.. 2 of which are his bio and 1 who isn't...
Our 2nd year of marriage I drank too much wine one night and he came home and rapped me.. i didn't know until the n2xt morning when I found my shorts beside the bed.. He went to work as usual and I figured it out and left with the kids to a hotel for a few days. He always pretends it never happened or he has excuses like you were my wife and I was attracted to you while you were passed out.. moving on..I caught him posting a question wanting to get rid of my son who isn't related to him.. would be his step son.. says he is too much work to deal with him and he's messing up his bio children.. moving on from there we went recently on a family vacation and my sister wasn't wearing a bra the entire vacation and hubby was staring the whole time.. after we got back home from vacation hubby looked up on phone.. " why sister in law isn't wearing bra in front of me" I always felt he had something for her because he was always acting different in front of her.. these are the 3 things that give me so much anxiety.. not sure what I should do or am I just overreacting?

People will be on with far more practical advice OP, but you need to leave this man. He has raped you, it sounds like your child is rather unwanted by him & perhaps even I danger, and this man's attitude to your sister is disgusting.

Please get out, you & your children need & deserve better.

Red lines for me: hurting kids...what he says about your son his step son deeply disturbs me and this is for me would have been enough to break up with him and believe me I am not in the LTB camp-on the contrary...your son is physically and emotionally in danger: focus on his well being and the well being of your other kids... now it is URGENT That you go and see your GP, tell him.how this man views your son his stepson, ask for a referral.to Psychologist for this poor little child...this child might or might not have little disorders (ADHD etc) that make him.difficult to raise. There are treatments that can help you raise him. Try to direct your focus on the well being of your kids...they are more important than anyone else and yes more important than yourself and this man-LTB unless he is willing to go through therapy and become a good father to ALL your THREE kids -with no distinction...once he is a good father to ALL of them then you might start considering rebuilding (with the help of therapists) your relationship ... until then break up with him..

It's quite disturbing reading OP, you must protect yourself and your son and leave him! Your son appears to be in danger with this man and you have to protect him. He's a disgusting man and you are not worried for no reason. Put plans in place and LTB

Please, please get in touch with your local Women's Refuge - you can walk into any police station or even a firm of solicitors and they will be able to help you find your way there. At the refuge, you can just turn up in the clothes you're wearing and nothing else. He will not know where you are. If nothing else you need to get these 3 children into safety.
