Dear Maia,
I'm sorry you are feeling so much pain and those bittersweet memories...you are remembering the good times too. 26 years....Hugs! He's still in there, but he has a disease, a sickness.
Zoso is right, your husband DOES have feelings, might not want this divorce and is trying to numb those feelings, any feeling he is having. He likely is hurting too.
So you're going to live together? How are you feeling about that?
Hugs to you and I hope your pain dims as the days go by,
TF
