Tell us about the boundary regarding the emails. What exactly did you say and what were the consequences?
I don't think your W is doing all that great, as you may think. She's going through stuff too. Her thought process is screwed up and this new body image is something that some women need C to know how to handle it. Some people don't understand it, but it's true nevertheless.
I don't get the back & forth contacts over the bills. Can't you spit them up and get on with it? Is it b/c of the "way" she wants them split that you don't see as fair? That has been the biggest issue, it seems.
About taking chances meeting OM at gym b/c you go there also......don't fool yourself. You'd be surprised at what some WAW's in an EA will do to get their "fix".
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
