Sounds like a MLC. She is establishing a new life, and will leave you with the kids as much as possible. You need to start on some 180's, take the kids fishing, swimming, etc. And just invite your W along. Be prepared for no to be the answer, and just act as if and go have fun. The infidelity forum may have some different advice, but not the traffic of newcomers.
