Can't you leave him? You can just run away one night, maybe. (I dont know your living situation so not sure if its possible but if it is, please do it) and also call the cops, when he isn't home, just call them and they can maybe help you out. Im sorry you have to go through this and if there isnt any way out of his SA, then, i honestly dont know. Ctb might be your only way out of it and its very unfortunate that you have to go through his abuse. I send you my best regards
