Show off!!!

1. I would find out the real status of his marriage/divorce.

2. Has he cheated on his wife before? His wife can be a great source of info.

3. Financial situation....by your posts he doesn't appear to be doing the sugar daddy routine with money. Your wife could be refusing.

4. Make night visits with the kids with say pizza or other food to have "Family Time".

5. Does he have kids? At 38 he might want some. Does your wife want anymore? Tubes tied etc

In the end all this may be for naught if she just wants out. You will have to weigh how to use the info or the sources (his wife) and how your wife will react to your snooping.
