I thought you kicked him out some time ago after he left rehab and started drinking again?
First, try not to assume his feelings are the same as yours would be. I see this over and over here...the partner bending over backwards to treat the alcoholic the way they would want to be treated. The Golden Rule is a beautiful thing, but nine times out of ten all it does is give the alcoholic another loophole to drive a truck through.
Second, please please don’t let him back into your home after this. You’ll be stuck trying to wrangle a possibly detoxing and probably relapsing person coming off psych drugs...you’re not qualified to do that and they shouldn’t be asking you.
You’re not married. You have no legal responsibility to him. If you go to visit him you’re going to be buying another ticket on the roller coaster.
Wishing you strength and clarity.
ETA: If you let him stay with you, I’d bet my car somehow that 8/1 rehab slot will magically disappear.
