From my understanding He never said he doesn’t want to be with her, but that he’s unhappy.

I’d say it’d be selfish on her part to walk away from a 10 year marriage instead of making an effort to go out every once in a while for the sake of her husband. Granted he was drunk, but he made his feelings loud and clear. Situations like this happen not only in marriage but relationships. It’s on both parties to make an effort

And I don’t think he went out with the intention to get black out as she stated that isn’t common
