Is AUTHOR wrong in the post ? POST : Context: I own a 2 bedroom flat and rent out a room to another guy (found him online), he's been living here for a year now. Overall he's a chilled person and I have no real issues with him. 

Recently his girlfriend has been over a lot. There was a point last month where she was round 9 days in a row. I said something to him at this point and that he needs to cut it down to 2/3 days a week max (the same amount of time my gf comes round). Unfortunately she lives with her parents and I think is why she spends so much time here.

The conversation went well and he was really cool and understanding. However now I've noticed she's always round on Fridays, Saturdays and Sundays - effectively the whole weekend. Technically this is okay as I said I don't mind her being round 3 days, but now I don't think I'm cool with her round the whole weekend.

I don't have my girlfriend round all weekend because I'm someone who needs my own space sometimes to relax. Therefore each weekend now it's sometimes just me and them two in my small flat. I don't want to feel like a third wheel in my own flat. If them two want to watch TV in the living room, I feel awkward being there. Obviously I would be fine with it sometimes but it makes me feel like a stranger in my own place for the whole weekend. 

Am I an arsehole to bring this up again and say it's not okay? I don't want the solution to be her chipping in for bills because it's not about the money: I'm just not cool with living with just a couple for the whole weekend every week. If it was a 5 bedroom house I think it would be different, but in a small 2 bed it's a weird dynamic.
