I have endometriosis, which is currently crippling me (been bleeding non stop for 19 days now)
So DH has gone camping for the weekend with friends (he's not the issue, he works 7 day weeks running his own business) on the occasion he takes a day off (rare) he will absolutely do his own laundry, my laundry, gardening etc when I haven't managed to do it because of pain.
The problem is his sister who lives with us! They moved in 3 years ago, his Mum basically kicked her and her boyfriend out as she wanted extra space (don't get me started on MIL).
I work 12 hour days, as does DH then he does his admin and paperwork when he gets home.
He works 9-5 from home, she is furloughed, NOTHING gets done, we've had numerous talks, they don't even empty a clean dishwasher, they leave their shit stacked up on my kitchen sides, their laundry by the washing machine, play Xbox in their room, never ever have picked up the hoover since they've lived here.
We agreed they move in for a year (3 years ago!) they saved to go travelling and went travelling for a year, the first year they were great, then came back to save again to go back travelling and covid hit. No travelling. So they've been in the house 24/7. They are moving out next month (thank the lord).
I got home tonight, DH away, they'd left to go visit his parents for a week 4 hours away, my house was a tip! I've been a mess all week with pain, bleeding, new medication etc. They left their pans with burnt super noodles in the bottom on the kitchen side, plates stacked up (I emptied the dishwasher last night 
), no water in the dog bowl, shit stains in my toilet, piled the recycling so high it's ripped over.
I lost my shit, called my husband, told him I was booking a cleaner for tomorrow as I'm in too much pain to lug the hoover about and clean and I sent a message to our group chat telling them they will be picking up the £70 bill. This is fair to me seeing as neither myself or DH leave dirty plates on side/don't clean our shit stains off toilet/don't leave our room an absolute dive/spilled orange pasta sauce from lunch on the cream sofa cushions.
They've read and not responded. They pay us £200 each a month rent. Food, sky, laundry products included and I feel like they've just taken the piss out of us since covid hit.
I've had an arsey text from MIL "I think booking a cleaner is unreasonable and to then charge them for it, it's very petty" sorry? I work my arse off, as does DH and I clean every weekend and do our laundry, this weekend I cannot as I am in awful pain.
Please tell me AIBU? I'm so sick of this all, the sooner they go the better!!!!!
