Hey Liz,
I'm glad to know that you all enjoyed your day yesterday, but it's not realistic hoping that one good day spent outdoors hiking as a family may be an indication that he's changed for good. There is a drinking problem, a porn problem, anger issues, little or no regard for you and your feelings to mention a few. Are you hoping that the light bulb will go off if you keep waiting for it and he will shed his outer skin like a snake and reveal the new improved him?
He told you if you didn't want to know the truth you shouldn't have conversations with him-Isn't he telling you this is it baby, my rules, like it or don't but you are staying. Didn't he tell you that he didn't believe in divorce?
