Mama, there is a lot of damage done in these situations, sometimes it can be repaired and sometimes it cannot. Each situation is different and it takes time to decide if and how you want to work on repairing it.
As I see it, he's working his recovery? and you're working yours, and that's a good start. But that's about each of you healing yourselves and learning a healthier way to live...only when you are both well, will the relationship become healthy again or the decision to end it will be more obvious.
I'm no marriage counselor, but I know the raw feelings and lack of trust, regardless of the relationship.
I hope you have better days ahead.
Hugs
