Hey @MRV welcome to the forums. I'm really sorry to hear about what you're going through, it sounds like it's been both painful and frightening for you. I get the impression your partner has made some extreme assumptions, and has closed himself off to open communication and resolution of any kind. It's deeply unfair of him to take it out on you - and it's never okay to resort to violence, especially when there's kids around to see it.
I'm glad you found us here, it's always helpful to have a space where we can vent openly and talk to others who may have experienced similar. You could also call 1800respect to talk it through with one of the counsellors there, they're super caring and trained to help support folks in situations like yours.
I have sent you an email to check in, so keep an eye out.
Also, we have some Tips & Tricks for newbies if you wanted to check it out.
I hope you find it to be a warm and welcoming community, feel free to pop in to other threads to say hello as well 😊
