Serious question

If your son (3rd boy/4th child) was a druggy, lived on the street, made excuses not to work yet always could get drugs, and disrespected you calling you a bitch, cunt, whore, etc... would you go and get him to let him sleep in your apt with you, your bf, your youngest son who is keeping a roof over your head, and your youngest sons fiance.

Now imagine all 5 of you in a tiny STUDIO apt. None of you can afford a bigger place or move out either.

Also the homeless druggy son is 30 YEARS OLD and throws a tantrum if you don't get up and take him wherever he wants when you worked from 4pm-3am and have work at the same time the next day.

Well my future MIL does this. Her son abuses her like this while me and her youngest yell at her to stop. We've tried moving but we just got new jobs and everything from a studio up is $1200+. Plus it's now the end of summer and nowhere is available. I need advice. Please help.
