I would move

yes it is

because you are a renter and not her family or bf.. you don't have to do their chores if you don't want to don't think it entitles you to free rent .. if you like cleaning house clean someone else's house and use the pay toward your rent.. or you can tell her you are charging her a cleaning fee and deducting it from your rent to her .. that might force them to make an effort to do things themselves instead of leaving it to you

Just ask for the rent reduction

That's ridiculous. It sound like they find it easy to take advantage of you. You need to find a new place to rent. You'll have less chaos without all the rotating roomates who refuse to clean up after themselves. But people always get ticky when they find out they're about to lose the one they see as their "cash cow". Mums the word you're looking and be careful moving out.

Time to move on and out.

the landlord should be informed, they own the property and approve who lives there....and doing so will make you the bad guy. be strong👍

Haha what you should do is just leave. You're being used as a servant.

Where or what country are you living in, seems to me this house is OVERCROWDED I would sling my hook find another place try spareroom.com there's only so much one can take surely.

Sounds like a bad living situation for you.

Your friend is letting you down and treating you like a slave.

Sounds like they know you’ll do it if they don’t, and they’re all about taking advantage.
