I'm going to tell my friend I cheated with his girlfriend.
Did you really cheated with his gf?
One night I was drunk and he left me alone with his gf, when he came back I acted as if nothing had happened.
You should not ruin someone else's relationship because you feel guilty. It is wrong to betray people you care about they might get hurt if they find out.
I don't care about others, F_ck them all.
You should apologize to your friend instead of being so insensitive about what you did to him.
