I really don't want to hang out with my mate this week. He wants to come over.
Are you fighting or something? Why don't you wanna see him?
I don't like to spend time with him anymore, he has a money problem. He also smells bad.
So it's his money problem and stench that puts you off?
It's not that bad. I would rather do something other than spend time with him.
Tell him how you feel. Be polite but let him know you're no longer interested in a friendship.
