how do you politely tell your boyfriend’s female flatmate to stop walking around naked

also it’s his ex

and when i mention it she’s like

‘HE’S SEEN IT BEFORE’ which makes me feel worse

or when i say ‘how’d you feel if your boyfriend’s ex flashed her fanny around him’

and she responds with ‘but that’s DIFFERENT i hate her you’re my best friend so it’s okay’ and completely disregards my feelings

like did you ever stop to think that i also don’t want to see that

put some fucking pants on at least

i don’t care if you live here i live here too and i’d rather not see your lady bits and i’d really not like for my boyfriend to be forced to see them

i don’t go around in the nude at my house in front of my family jfc what kind of family did you grow up with
