So Rita at McKesson calls my husband to set up a time to cheat...?

This female Rita works with my husband- her boyfriend also works at the same company. She called my husband to set-up an affair one day at 6:30 a.m.. I heard the whole conversation and have decided to leave my husband. I blame him as well. Here's my question; should I tell her boyfriend (who also works with her and my husband) she's a ? He always calls my husband seeing that Rita's boyfriend and my husband are friends. Rita's boyfriend is black and she's asia- he brags all the time about his trophy girlfriend-little does he know she's an Asia tramp.
