I believe that are at least two women on this site that were WAW that are trying to win their ex BS's back. The men now have another woman. I read from one of them that said THAT was the thing that woke her up.
My observations over the years has shown me it can be an effective tool. I am only talking by observing what the "reality" shows. It seems to me that women are very competitive about a man when he seems to have an interest in someone else and not her.
I also have a suspicion that many men who are on this site are secretly checking out the "dating sites"
It seems to me that the men who have the most success are the men who move on the fastest and refuse to chase a woman that says or shows she doesn't want him. When he shows by his actions that he gets the message and leaves her alone, she then isn't so sure she made the right decision. My observations in watching the reality, is that he convinces her more quickly that he has let go by seeing other women. I don't mean instantly clinging to one woman. I mean going for coffee. Going to a movie. Being seen around town out with one.
I don't want this thread to turn into all or nothing. I am only talking meeting and mingling around with women. Or even as Puppy has suggested, the "idea" of her thinking you may have something going on....
