The lie continues...

[ForGump]

I don't see it as an easy call ... but I think you did the right thing, telling her you know. The key, as I see it, is that you told her (fairly?) calmly and w/o much emotional baggage. So (I think) you made it all about honesty, integrity and loyalty, not anger and jealousy. That seems the right thing to do.

Hopefully she'll "woman up" and start being honest with people in her life.
