I am no vet, and am dealing with a WAW having an A and not admitting to it...but I would stay away from dating. If you really want to, then perhaps you should not try to save your M? My guess is the vets would say that you need to find yourself and detach with friends and hobbies, but not because you find another W. If you get so much confidence from seeing another W, then you probably are not detached from your W? I don't think it should take another W to help your recovery and detachment.
just my two cents...
