Scarlet, I understand how it would feel like H's job is more important. But he hasn't been there that long, right? I know one job I had, I wasn't allowed to take even sick leave for the first 90 days because I was on a probationary period. So if he were to take off or step out of a meeting to talk with you, then it could potentially put his job at risk. And his job is what's allowing you to do therapy twice a week, right? He also may not want to guarantee something he doesn't know if he'll be able to provide (like if he's in a meeting and had to have his phone on silent).

Is it at all possible to schedule sessions for when your H would be available? Like, so they'd end around the time his lunch break is starting or when he's getting off work? I know L's schedule sounds pretty booked, but I wonder if she'd be willing to switch a flexible client to a different slot? (Dr. T has done that with me on occasion, asked if I could take a different slot that week, though he never said I had to change, unless it was, say, a conflict he had with his own doctor's appointment or something.)

I will say that your dad's response sucks, especially as he doesn't work, right? So he should at least be able to take a phone call from you.

Is there anyone else you know who you could talk to? Even, say, a cousin or old friend who you aren't all that close to anymore, but who might be willing to be a sort of emergency contact?

And please note that I think your feelings are completely valid here--I'm just trying to suggest a different perspective regarding your H.
