Not now, he doesn't. Maybe someday he will.
Right now all he can see is that his world is rocked and you are the bad guy "doing it to him." He sees himself as the victim. He HAS to see it that way, because it's too painful for him to see this as something he has brought on himself.
He sees NOTHING WRONG with the status quo--living under your roof, as he pleases, making demands of you and having tantrums when he doesn't get what he wants. He doesn't "get" why you should have a problem with that.
And aside from the inherent selfishness of addiction, he has no concept of what it is like to be an adult like you--someone who goes out and works hard for what she has, someone who has a EARNED a nice place to live, and a place to relax after a hard day at work. So he has no appreciation of what he is taking from you.
I hope you are able to get out of the house a bit this weekend--otherwise you will be subjecting yourself to his negativity for two whole days. Can you find a couple of Al-Anon meetings? Go hang out with a friend for awhile? Go out to the mall or catch a movie or something?
Hugs,
