My wife has a new cell phone. Since the birth of our DD my wife and I have had a cell phone which she keeps for emergencies. We are not cell phone people and have thousands of minutes on it.

Recently my wife's purse fell over and it dropped out, she did not see I just cleaned it up and stuffed everything back in her purse but found the cell phone with the area code of OM. It was a gift to her from OM who she plays with on a computer game. I have no direct evidence of an affair other than racy emails and evidence of cybersex which she says is just online playing and denies physical interaction. I know she has met him as my wife has gone alone to Online Gaming conventions and know he was there.

I have not talked to her about it but did secretly look at phone and OM is the only other person on it.

I plan on confronting her but not sure how to go about it.
