I'm going to tell my friend she should be more honest with her boyfriend
Why do you think your friend lies to her boyfriend?
She lied about us hooking up
It's wrong to tell your friend her business when you are the one helping her cheat. You should be the one to apologize to the boyfriend.
Um no I don't think so. The fact that she denied cheating even though we had sex is wrong.
The entire situation is wrong, you both are guilty. If she doesn't feel like telling him she may be getting ready to break up so keep your nose out of it if you don't like the situation.
