Yes. Everything Anvil said.
You are letting yourself be lulled into complacency by staying close.
Here is your post after you left:
He came and cornered me in the back room and put his hand around my throat. I said to stop or I'd scream and he said to stop or he'd break my windpipe. Just then my son walked in and he stopped. I'm out, and I'm never going back.
A couple of days later, you said you get sucked back into his "help me BS" every time you see him.
I can't find the post, but again, a few days later, you said he didn't try to choke you but he pushed you into the wall.
Do you see what you're doing? You are talking yourself out of your own experiences. You're telling yourself that incredibly frightening thing didn't really happen the way you remember it happening. You're getting sucked back in.
Take time off work or school if you have to. Don't spend time worrying about what may or may happen when (if) he gets sober or the kids get passports.
Right now, it's about staying safe. Staying alive. Don't go back there. Booze and cocaine and ativan? Sounds like a recipe for disaster in my book.
