Vent away.
That's what we call the alcoholic quacking (one of our lovely members always reminds me to picture the AFLAC duck quack quaack quaaaaacking whenever they do this
) Sometimes the BS is incredible, isn't it? "It's all your fault I screwed up my life!"
It's designed to make you feel bad, and if possible guilt-trip you into changing your choices so they are better for HIM.
I know it's miserable, lettec, but all the more reason for you to let him go back to wherever and continue to ruin his life the way he was before you let him move in with you. Sometimes this is the only way WE learn our lesson: let the alcoholic make their own choices, and don't save them from the repercussions of those choices. It doesn't do anyone any good.
Sending you hugs - you will get through this and be stronger on the other side, if you let yourself.
