You have found a great place for support. Many here can give you insights on things you can do to improve the odds, but ultimately your H will need to have a change of heart.
Focus on things you have control of. Take a hard look at yourself. What would you like to change? Start making positive changes each day. If you find it hard making personal changes, think how hard it is to change someone else behavior. Don't try to change H. The best thing to do is change the way you interact with him. It will force him to interact with you different.
Embrace this process. It is the best worst thing that happened to me.
Let us know how we can help.
