I'm going to tell my partner he can't hang out with my friends
Why don't you want him to hang out with your friends?
I just don't want him to hang out with my friends.
It is rude to ban your partner from your friend group. You should be kind to them and try to encourage them to make new friends.
Fuck you.
There's no need to be rude, I'm just saying that there's nothing wrong with your partner hanging out with your friends too. You should share friend groups and try to all get along.
