What advice are you looking for here? I mean, to me the answer is obvious: leave. This guy's manipulative and abusive.

• he decided BIL would live with you without bothering to clear it with you first. Oh, and BIL is a freeloader so you're paying his living expenses too.

• he then claimed you were just as bad because you ... got skin care treatment without telling him? Oh, dude. Yeah, that's not the same as having an entire extra person living in your house.

• MIL also lives with you. I'm gonna guess you weren't consulted about this either and hubby just presented it to you as a done deal.

• you have a demanding job and have to work late frequently, which is hard to do because MIL is sleeping in living room and hubby goes to sleep early in bedroom. So you work in the dark to avoid inconveniencing all these people who are not concerned about inconveniencing you.

• he took your laptop from you when you were in the middle of doing work, and refused to give it back. Then he got physical and hurt you.

Yeah.

No more evidence needed here. Leave.
