Just need to vent.

This is my wonderful BIL. I left my job because my PPD and PPA made it difficult to handle the suicide calls that spiked during covid on a general information line. Apparently because I'm home right now means that all my fiances responsibilities at home stopped and I became a single parent with a roommate. All because my fiance said no to taking his shift. I'm tired of this. He just ignores when shit like this. I have 3 under 3 and every time they offer to take them they are on us in 2 hours or less. Mind you I'm trying to potty train two 2.5 year olds. I have an almost 10m old as well who, while he refuses to say mama, is very much a mama's boy and is very very clingy. Which is different to me because my twins have always been very independent. I very rarely get any time to myself unless I'm asleep. Is it too much to ask that I get help around the house while he's home?
