You are an amazing and very loved woman. I'm sorry your H is too blind to see what he's losing. I do feel in my heart that he will see that some day.
Surround yourself with loved ones, and hear their words of praise about you and let the love in their hearts fill your heart up, because yours has sprung a leak. They will be your strength to carry you through. (We will, too, of course.)
This flawed man doesn't define your worth. He's searching for something and I don't think he can find it in a person. But he's going to try, apparently, all while hoping to keep you on the line as he takes risks to build up his ego.
You are no one's safety option, and I am glad that you see that. I'm sorry that your H doesn't see it right now, but he's not looking through clear lenses.
Lay down those boundaries about how you will allow yourself to be treated. Don't show him your cards or tell him what you know.
