My wife got a new best friend on Facebook (woman) and fell in love with her. The friend did not fall in love, it was one sided. That friend was having an online affair with a man and also got my wife to do the same with same man.. That has ended and my wife wants to stay friends with the woman. Why would my wife want to stay friends with a woman that almost ended our marriage when she says she is no longer in love. It hurts me every time they communicate and reminds me of the affair.
