I messed around with my best friend who is a married girl.
Do you think that was the right thing to do if she was married?
I don't think it's that's bad!
Messing around with someone in another relationship is wrong. This destroys the other person and their relationship.
She's already a slut anyways, so what difference does it make.
It doesn't matter what type of person she is, it is still bad to cheat on others. I can understand it takes two people to have an affair, but you should be the bigger person and say no.
