Dear Teresa, I am really sadden about this story. These two sound like something is going on to me! They will eventually get caught or it will just die out. Meanwhile we have little children caught in the cross fire. You might tell them about what happened to you and how your ex is having to pay,pay,pay. You might mention how your husband thought no one knew but everyone knew and how he thought he could have his cake and eat it to. Let them know how it destroyed everyones lives and the impact on the kids. Let him know about not living with the kids and fighting it out in court. Just kind of telling them your story if you feel that is not to personal. This will help drop a hint that you suspect something and what can come of it.
