Gaslighting, already.
There is completely, absolutely, unequivocally NO REASON for an alcoholic to have alcohol around their place or to use products that contain alcohol when alternatives that do not are available. He is likely active, still, (and lying straight to your face through innocent "see how transparent I am" expresssions that addicts are famous for) but setting you up to get sucked in when you're hooked into the relationship and he has his first "relapse" in 25 years (cough, cough)...
And then blames it on his depression...
If you're still involved with him in six months, make note of this thread and come back and read it, then.
That you are generating red flags is appropriate.
