Why did exW file for a review of child support when SHE is making more money? Does she not know how this works??? Or does she think you are making more in just 12 months that would offset her increased income?

An adult vacation sounds like a great idea.

Also - bear in mind - your marriage was already broken when OM2 showed up on the scene. This really isn't about him but about her. Keep your anger focused on her, she's the responsible party.
