Another thing I'll add as it's important. I may have already mentioned it but it's very important so I'll mention it again. While me not engaging in life in many different ways (making new friends, new medication, driving, family, etc) is a very important aspect of M2's demise - I want to be sure to not take the spotlight off of the disconnecting and/or "retreating into a cave" part of my life. This is specifically what was brought up by X2 a number of times near the end. I feel that working to reconcile M2 would have had a chance if I had not been hibernating in my cave. She specifically noted that she was not going away for the time being but that she was not going to come in and pull me out of my cave, that I had to come out myself. The reason why this is critical to note is that one of the issues I had with how she handled D was that she didn't communicate enough about how she felt thus not giving me the option to make changes as I didn't know how dire it was. Well, taking into account her "cave" declaration I am wrong. While she didn't specifically say if I stayed in my cave she would file for D she made it crystal clear that she was no longer going to go looking for me and that I would have to come out of my retreat on my own. If I did that, if I "heard" her, I feel we would have had every chance to actually work through all the other issues and end up with a stronger marriage because of it.
