Ok. Good job. What about someone she works with? What about an internet contact she is corresponding with? What has she been up to on her weekend without the kids? Do you think she is just sitting home by herself all weekend?
Keep digging. If she doesn't have a crush on another man, then you are in much better shape than if she does. You need to be like a private investigator until you know for sure. Explore all possibilities.
I am not trying to make you feel bad, but a woman almost NEVER leaves a man unless they have interest in another man. It is like seeing the same movie over and over.
