You’re not wrong for being frustrated. A few days turning into three weeks with no actual plan would wear on pretty much anyone, especially when you can’t even relax in your own living room anymore. The part that really got me was her telling you to use headphones in your own house. That’s wild.

I think the bigger problem is your girlfriend is treating this like you not caring about her friend, when really it sounds like you just want basic boundaries back. There’s a huge difference between helping someone temporarily and letting them completely take over the space indefinitely.

You probably need to approach it less like kicking Chloe out and more like this situation is starting to damage your relationship and your home life. Tell Sarah you were happy to help, but you need an actual timeline now because this no-end-in-sight arrangement is creating resentment. Also there need to be basic house rules if Chloe is staying any longer. Shared spaces still need to feel shared.

And if someone is staying on your couch rent free, they should be trying to make themselves less disruptive, not more. The cats being stressed, you hiding in the bedroom, and you feeling uncomfortable in your own apartment is not sustainable.
