I want to sleep with my friends wife
Why do you want to sleep with your friend's wife?
Sometimes I think of doing it like a revenge on my friend, I am fed up with him and want to ruin him.
It's important to respect other people's relationship. You should never sleep with a friend's wife.
Don't tell me what I should do.
This is not a way to get back to your friend. If you have any problem with him, try to talk to him and sort it out. It's not ok to ruin their relationship for your revenge.
