This is great Sparkle! You sound like you are really getting a handle on the "Fake it to make it" interactions with H. I am not there yet, I feel like I will break down if I have to talk to H, so honestly I have been avoiding it.
The fact that you are able to present yourself as collected (even if your brain is a hot mess) is a truly great step.
Patience and making assumptions is a struggle for everyone. I try to think about how I react sometimes. Do I always say what I mean when talking to H? No, of course not. When I get hurt or angry I say things I DON'T mean (my goal to work on). Or when I feel vulnerable I don't share what I really am thinking/feeling. So why would it be any different for them.
