Little my dear it is not over until it is over ie: one or both of you is dead. But for right now you need to just try to get back on your strong, awesome, confident feet. He has a lot of work to do changing himself. And it doesn't even sound like he recognizes that! So it would likely be a long road until you two can work on things.
So for right now, focus on yourself. if you need to be sad and cry that is fine. If you need to be alone with a bottle of wine, go ahead. If you need a hug from a friend, go find one. There is nothing you can really do for or to or with him now. Just let it go for now and see what happens.
I feel for you. I have been in this really sh!tty place before for sure. It is low and terrible. But you will be ok, and sooner than you think.
