Apparently dating can be a good strategy to help the WAS realize what they're losing. So I guess it could be seen as doing what works.
I could see people doing it when the situation has been going on for a while, one or the both of you have filed for divorce, and you're ready to move on.
I agree with Karen here...if you've dropped the rope, given up and are truly moving on, it's fine. If you still want your M and it's just a tit-for-tat thing, which it sounds like, not sure it's a good idea.
