I totally get this. I finally started taking my kids to those cute junky little "German Towns" with a waterpark because my stbx was always so busy at work, stressed, etc... we finally convinced him to join us for a weekend. I know it wasn't the posh hotels and cool stuff he was doing with who knows who, but the kids loved it and were so excited that he joined us. As was I. Found out later that he was emailing the entire time with his young office girl entourage about how sucky it was, how lame, they all thought it was hilarious.. The kids will never know, but it still gets me and hurts to the core. Mofo.
Anyways, loved you vent!
