Alicia, erin gives good advise. My two cents for what its worth...
Our Dx's are not thinking of us and our relationship, they are blocking us and it out as it makes them feel bad, guilty or whatever negative thought we can use to describe/imagine how they are feeling...
You e mailing (in my opinion) anything related to that is only going to remind him of his negative thoughts, make him withdraw more, feel more guilt, etc
I really understand your wish/need to do this and did it myself with no positive result, reminding them of negativity only pushes them further away-I think this is where my x thinks I am BAD for him...
I think the only way to try for contact is to put your feelings away in a box and e mail him asking how he is, telling him how wonderful your doing, how life is good blah blah blah, removing the guilt for him... and pretending that all is well... Can you seriously do that? Its like not being able to feel/show your true feelings and emotions but I think we all have to recognise this may well be what life would be like some of the time with our xd's.... Is that what you want for you? I have never met you Alicia but can tell you are a wonderful, kind caring person by your e mails and writing, you deserve to be with someone who treats you in the same way, we all do....
Do whats best for you..
Big hugs
Hanik.
