Hidden Facebook?

Me and the wife split up after she cheated on me and lied about it. Here we are 3 years later supposed to be working on our marriage and a friend of mine says that's a nice picture of your wife's Facebook and I replied to him that she don't have a Facebook. Now a couple days went by and I'm thinking I better look into this and I do, guess what he was right and she's friends with our children which means she had them lie to me for her. My question is ladies and gentleman does that seem to be working on a marriage? What's your thoughts on this and how would u deal with it?
