Silverberry, sometimes anger is an appropriate response.
You, for example, have to come home from work to face a cheating, snivelling, self-pitying alcoholic who used to be a man. That would make me mad enough to scream. Oh, wait, it DID
Make a plan for what happens if he's still there when you come home. Explore your legal options. Write down the monthly price of the nearest storage facility that rents 10'x10' spaces, and give him their number. And make sure he knows that NOT leaving isn't an option. Helping him with boxes and such is a not-so-subtle hint too that you're not going to back down.
You just have to survive this. You can do it. And just beyond that --- all the possibility in the world for greater joy in your life.
