Hi BF, I'd say when we feel like a doormat, (notice I didn't say when OTHERS see us as a doormat) then there is some truth to it. As such, I think it's important enough to address in some manner. For me, it would be finding a way to feel some control over the situation. Say or DO (or refuse to do) something that shows me standing up for myself.
It seems maybe you fret over your every word, text, email a little more than you should. H certainly isn't doing that! Maybe just be yourself and do/say what YOU want. What works for you?
You already know you can't fix H, I want you to know you really can't mess this up either.
Be brave, be you!
IDK how this sounds to you, but it's been working for me.
