unemployment

So my husband lost his job in April he was going to school to become an Emt in the meantime he got unemployment and still finished the classes, got a job at a call center and left bc they didn't want to work around his school schedule. I'm fine with that because becoming an emt was the main goal and he was getting unemployment. Long story short his unemployment has ran out and he has like 3 part time jobs well 2 now bc he quit one. I have no problem supporting him but I feel like he's leaving me out to dry with bills we have 2 kids and one on the way. Im pissed bc he shouldn't have quit a job when he doesn't have income coming in like that. When he works he works but I have no clue what's going on..idk how to feel about this but I'm extremely pissed. I would never do this to him we are a team and sometimes you have to sacrifice. I understand what his goals are but we all know sometimes it doesn't work how we want it to..Sorry so long
