You handled yourself really well, especially your composed response to H's 'he won't recognise my voice'. Good on you!
I'd go to his graduation. It's give and take at the moment with you guys. He's working hard. So you can give an inch when it feels right to do so.
Really sounds like your H has a clue or two about what being supportive means...I mean, that wasn't at ALL the case the last few months, but maybe he's clearly working on it.
best, all the same, to be cautious.. he's done it once and it capable of leaving you in the lurch again (sorry, don't mean to be blunt but think it's important to take care of you and be wary and openminded at the same time).
HUGS!
