Eh, screw 'em.

Well, seriously I say have a talk with your boyfriend after you've both calmed down. Maybe he's stressed about money since you're not working? Maybe he just snapped and didn't mean what he said, maybe it was said out of frustration. I'm NOT defending his actions. Rather, I want to give another perspective that things may not be so dire (i.e. He doesn't support you at all).

As for your dad.....ugh. What does he want you to do? Just go out and become a CEO right off the bat? EVERYONE starts somewhere. And it sounds like right now you should be starting off at a low stress job like working in a pet store.

I think it's hard enough for us to accept our own limitations but it can be even harder for others to do so.
