You do NOT "know" that that is him on that site.

Word to the wise from someone that's played a similar game, DON'T pose as a stranger and contact him. Life ain't like that Pina Colada song. In fact, stay off that site PERIOD. This is not a game and therefore you can never compromise your integrity as a stander by doing something like this because it WILL backfire on you. I can not express that enough. Even though my sitch is different - I was a MLC/WAW - I did something like this to get my husband's attention and it SET MY SITCH BACK AN ENTIRE YEAR. He will turn this around on you. Don't do it.
