What an email... I understand the desire to know what is going on with him ... to wonder what he is thinking and doing... to wonder if you have anything to worry about... I can tell you that it is such a relief to not have to know! My H and I work at the same place and our offices are next door to each other. I can hear his convos and phone calls if I care to pay attention. In the beginning I wanted to know what he was doing to prepare myself for any unwanted events.
But at some point I let it all go and I feel so much better. Anything I need to know I will eventually find out and the rest doesn't matter. From experience I have learned this. Please think about letting go more than you are. It is so much easier not wondering anymore.
