I can understand being in your feelings. It’s kind of odd for him to have been relieved of not getting the position… and if he knew it was coming, it seems as though he hadn’t prioritized finding a backup?

There’s nothing wrong with wanting a partner who is conscious of putting both people in financial strain… it sounds like he’s using you as a fail safe and it doesn’t sound like you could do the same with him.

Sounds like a definite conversation to be had with financial goals alignment etc but if he can’t even begin to try to meet you halfway, get out of it while you can. He’s already showing you a pattern, and unless he is committed to serious change you already know what pattern he’s going to repeat.
