Your H is going to have these same problems with every woman he meets IMO. He has to look at himself to fix himself. And hopefully you have been and still are improving. Maybe your H will see that one day and decide to change, and maybe not.
I hope you get out and meet some people and have fun and enjoy life in the meantime and try your best to forget about this guy. I think you don't have to "date" per se, but that you should get out and flirt and have fun and just let the world remind you that you are attractive, important, and wanted. That will do so much for your mindset. I'd find a way to make that happen. Get a sitter, etc.
When you look back on all of this, you're going to wonder why you were so easy on your H and why you let him get to you all these times.

It is not things that bother us, but the stories we tell ourselves about things.
