A friend of mine's DH left her for another younger, childless woman about a year ago, and recently OW has been spending more and more time with their DC. Friend is devastated by whole thing.
Friend wants to meet OW to try to move on and also so they can be friendly with each other if she is going to be so involved in DC's life. I wouldn't be surprised if her dickhead DH spun the usual lies to OW about their marriage being over way before it was, about DF being a horrible person etc.
He lied to DF when he left saying there was no one else, when he'd been having an affair, so he has form.
Is it a good idea for her to meet OW?
YANBU it's a good idea
YABU no she should stay away from her
