Wow. Nothing good will come of that. This will just make everything much harder on your kids.
Your wife has secrets too. You have been on this site for 6 years, you can be sure that she has been in an affair for at least that long. SHe moved out and went to OM and you believe her that she didnt have sex with him? Hard to believe. You mentioned that you cut off contact with your family essentially so that your kids wont hear about their mom's inappropriate relationship with OM from, what, 8 years ago? Why do you feel the need to throw yourself under the bus yet go to such lengths to protect their mom?
