I also cannot see one point that you made that would leave me to advise you to stay with him.
On top of that, i would not leave him unsupervised with the kid(s).

If it were me giving advise to my best friend who told me all of this, i would tell her to kick him out, get a restraining order for her and the child and start divorce and custody proceedings. I would say he is in need of support for his addictions, anger problems and overall mental health.

There must be another side to him that you havent described. But based on all of that, i wouldnt even leave him alone with my dog.
Im sorry for being so blunt. Especially if i am misunderstanding.
