I don't want my partners friend to stay over as much
Is there something wrong with your partners friends being over too much?
I think it's quite an annoying thing when your best friend stays with us in my place. He complains about everything, creates mess around the house and acts like he knows everything better than everybody else.
You really should try to respect your partner and his friends. He makes him happy. You should get along or at least try.
He annoys your fuck out of me, I want to discourage him from coming over.
It sounds like you need to talk to your partner about his friend if you really find him this annoying. You wouldn't want to let him come between your relationship and working through this issue sooner is better for all parties involved.
