I dont' know if I have ever posted to your specific situation but your is one I read. You always get great advice froom your friends here.
Your road has been hard, I can only imagine your feelings even though we have both been betrayed by our H.
You ask early why your H still treated you so badly well:
I would like to remind you of the old saying:
People treat you how you let them treat you. Your in control of that but yet you keep expecting him to change. He knows you will allow this behavior. So he will continue.... it's up to you to change the dynamic.
Blessings,
