mel, If you do decide to post a response to him, just say "I'm sorry you feel that way" and then let it go.
As for him no longer having the need or the passion to give you what you want, that's the mlc/depression talking. It's killing him to see your level of commitment and that is called "guilt".
You know what was real in your marriage and you also know that some of the garbage that spills forth over his lips is garbage. When in crisis, they only see black and white and there is no middle ground.
Read as much as you can on male depression, as well as mlc. Do try to keep the focus on you as much as possible.
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.
