"He can't keep a job"

So my boyfriend and I have been together A year and a half and during that whole time hes been struggling to keep a job! I moved into his apartment last may with the agreement of I'll take care of food and groceries and he'll take care of the rest. Up until this point, although he has struggled to keep a job he's had enough money to take care of everything. Now his funds are running low and I've had to pay rent last month and probably will have to this month too I'm starting to resent him, bc he knows I took this promotion at work bc I need a new car and I'm trying to go back to school! Also while I'm busting my ass managing two different restaurants working over 40 hrs and dealing with so much stress I have chest pains headaches and don't sleep through the night, he's sitting at home. Yes he does look for jobs and have interviews but his work ethic is nothing compared to mine I started working jr year of highschool and never been without a job since!! He's very stressed and a lil depressed about it, but to be real he's put hisself in some of the situations to get fired but he honestly doesnt see it that way! Nothing's his fault! I just have a hard time figuring out if I'm suppose to stick by his side even though, even though he's hurting and kinda putting my goals and dreams on hold. Or if it's time to cut it off. We're not really moving forward we're just stuck! It would be nice if as a man he would want to help me out and take some stress off of me.
