Red flags everywhere with this guy. I did a copy and paste from the first half of your post of the things that jump out at me most.
He is a very heavy drinker
and encouraged me very much to drink as much as him
it was great and also a little bit tumultuous because I found he was very controlling
being fresh out of a divorce, my boundaries were very blurry
he wanted the items he bought me back
stating to myself several times I hope I keep my boundaries with him
codependently, getting back together was awesome
He was an “disability“ for his legs which he was milking the insurance company for benefits
he pushed me at an amusement park last August and this was after I was in a terrible accident (That's pretty bad!!)
I decided for sure I was not going to live with him
...Yes your emotions will be all over the place as you sober up but it's not like you have no grasp of reality at all. Go over your post carefully and imagine it's someone else's post. What would your response be? That might help.
Congratulations on your sobriety, and best of luck!
