She lied about breaking up with fiancee and cheated with me. Do I tell him the truth?

[Quiet Storm]

She sounds like a Borderline.

 

Tell her fiance, but he probably has already caught her in lies, too. People that tell these types of lies don't just lie to one person- its part of their character and they lie to everyone.

 

He deserves to know the truth. He should know what she is capable of before he marries her.

Fiance = male

Fiancee = female

[phineas]

just move on

 

nothing good will come out of telling her fiance what happened

 

Unless you have pictures she sent you naked to show the guy i'd have to agree.

 

Most people won't believe or don't want to believe a stranger telling them their significant other is a cheater.

 

It's a waste of time & you might end up getting beat up.
