Destiny, He doesn't care because he is in depression/crisis. They are all into themselves when they are depressed and when the crisis hits, goodbye spouse, hello "me".
The man and marriage you knew and loved are no longer there. If and when he comes through the crisis, you will know then if he is the same person or someone totally different. Many of them come out the other side w/some of the characteristics that they picked up during the crisis. Others will be calmer, more mature w/a better understanding of where they need to be in their lives; and then, there are those who remain stuck.
I strongly urge you to go back and re-read your entire thread as well as the resources thread. Maybe this will help you understand that nothing you say or do will change his course while he is in crisis. You are expecting him to be the same person pre-crisis and that's not what is happening...your expectations have to remain at ZERO at ALL times.
It is very, very important that you keep your focus on you. Live your life to the fullest and if he wants to tag along, fine, but keep your expectations at zero. His crisis will not end today, tomorrow or next week. It didn't happen overnight, it will take a lot of time for him to work through it. The question I have for you is this...what are you going to do for yourself while he's on the Mother Ship? Make a list of things that you want to do, have in the works and need to complete and start working on them....this will take your focus off of him and back on to you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
