I am new here and just reading your post. My H is 42 and very likely going through MLC. I especially liked "Knowing when to talk about something and when to just let it go" from your list. That was also , I believe my biggest weakness. Controlling those urges can be very hard. I nagged him a lot when he dropped the bomb, but now I am calm, and somehow independent.
