Do you think "befriending" her on FB might make her take notice? At the very least, it might give you some peace. It think she is trying to do all she can to get under your skin.
What do others think on this forum? Should newpand take his W off of Facebook?
Hang in there -- we're here for you. Bob
newpand, yes, Bob is right. Unfriend your W from FB. Stay off of it if you can. Do not look at what she or others post. This is for your mental health.
And don't do things to make your W notice. Do things b/c they make sense for you, and your sanity.
