What Do You Do When Your Friend’s Husbands Hits On You?

A listener Lisa sent me an email asking for help. Lisa had her friend's husband hit on her and she was completely shocked! She thought they were a happy couple with very little problems.

She of course turned down the husband, but is not sure if she should tell her friend what her husband did? She is afraid that this could ruin her friendship, but feels that her friend should know what her husband did.

Should Lisa tell her girlfriend what her husband did or just forget about it?
