Those are questions you have to sort through, but right now he's not capable of being the H you married. So, let it go and just focus on yourself.
What are you doing to stay busy, to treat yourself well and GAL? Specifically, what are your plans for the week to take the focus off of H and onto yourself?! Set some ST goals and make it happen. You'll feel better and spend less energy thinking about what H is doing, what he says/does on FB, why he is treating you so bad, etc. I understand the feelings, but let's work on getting you busy so you don't think so much about H. He doesn't deserve this much energy from you right now.
