Welcome!
Since you have been lurking you know that no one here is going to advise you to leave. Only you know the answer to that. I am sorry this has happened but until you see him you don't really know. Well, you do but you don't.
Addicts hurt themselves too. Not just us and I will bet he is kicking himself. I would not jump him as soon as he gets home no matter how angry you are. That is one sure way for him to be angry at you instead of himself. He will be looking for a way to blame anyone but him...don't fall into that trap.
You could calmly tell him what you told us. That you will not live this way and leave it at that. That leaves it open to leave tomorrow or in a year. It buys you time to wait and see. It also is honest.
Since you know all of us let us get to know you now.
Hugs,
JT
