<human>: I injured my knee very bad during exercise and I needed a major surgery. Right now about a week after the surgery I'm completely useless. I need help with almost everything that needs moving. My brother moved in with me and he's gonna stay with me for the next few months.

So his girlfriend (dating maybe a year?) called me today and told me that this isn't fair on her and she was hoping he would move in with her and now that he's moved in with me that's delayed indefinitely. She said I'm an adult and I should take care of my problems myself instead of relying on my brother, and things like that.

I don't what to do, if I should mention something to my brother or not, if I should tell her something or not if she brought it up again.

Summarize the given text in a few sentences.
<bot>: My brother has moved in with me after my knee surgery to help me out. His girlfriend is apparently not happy about this and has told me of her dissatisfaction. Not sure how to proceed from here.
