We don't live together but he does sometimes stay here on weekends (and alternatively I sometimes stay at his house other weekends). Anyway he gets a bit funny about me going out with friends on weekends as its the only time we get to see each other (not true, we often see each other during the week for coffee etc too). So the past few times I've gone out he's asked if he can stay at my house so that he's here when I get home. No skin off my nose, if he wants to sit in an empty house all night until 2am then whatever!
Anyway I'm going out tonight and he keeps texting asking if he can come and stay here the night. I can't really explain my reasons for this but I just don't want him to. I want to go out with the girls and come home to my house, have the bed to myself, suffer my hangover in peace etc - I just don't want him around tonight. He doesn't understand as "what harm am I doing just sat in your house while you're out?" etc but AIBU to say I just don't want him here tonight?? especially as there is no specific reason for it, I just "don't".
AIBU? if not, how do I word it so it doesn't sound quite as blunt as "I just don't want you here"?
