Depends. Depends on what you want and what you're prepared for.
Several observations - the jealousy thing can work. As soon as my Walkaway saw a photo of me and Miss Someone, she wigged out - and immediately started paying lots more attention to me.
Date Person needs to understand - that is, you need to make crystal clear right from the get-go - that this is Dating, not Relationshipping.
You need to understand that "things" - that is, your M and your Walkaway - aren't going to look the same. You're going to be in a kind of fog of your own. I learned it first-hand. After a couple months of seeing Miss Someone, I've realized that WAW really isn't all that. In essence I've become the Walkaway. In my case I can live with that - most days, anyway. So unless you're prepared to meet someone better, dont do it.
