Maybell I don't have much insight but I just wanted to reach out. Take it one day at a time and enjoy dinner with no expectations as I'm sure you know
As far as what you guys used to do years ago and what you don't do now. My H turned the same way and it took BD for me to realize we both really were unhappy and stagnant not doing things we used to just going through the motions. Your H can get back there if he wants. He can be that man again IF he wants to. Those are all things that can come wth time, counseling, etc. try not to worry about that until the time comes. I know it's easier said than done but where you are I was a month ago.
I used to think of all the things he hadn't wanted to do and how much fun the bkys and I had this summer without him. I remmeber thinking why would I want to go back to that when I know I'm having a better time now than I did last summer. But the H that has come back to me (thus far - and it's hard to say it's going to stick because it has been not long at all) is the man that wants to do fun things because he is happy and most importantly because it's what he wants and what I want.
