Your story totally resonates with me. Like you I was receiving hugs, affectionate kisses, emails and texts with I love you through out our M and basically up until when he told me he couldn't rekindle the passion. Like you I supported my H through university for his teaching degree. How sad is it that our Hs couldn't talk to us about their unhappiness. My H told me he's been trying to find his passion for quite a while and like your H mine has also cried countless nights. Like you, there were positive elements in our M like companionship, friendship,shared happiness with our two Ds and we share similar interests, elements I thought would get us through this sitch but it wasn't enough. Last year, my H experienced extreme work stress along with our M issues. The work stress has continued this year. I was waiting for my H to open up to continue discussing our M and I was getting frustrated. He finally opened up to say he wanted out.
I too am feeling hurtful that my H is throwing away 14 years of M, our family of 4 and does not want to fix it. My H and I tried a few sessions of marriage counselling last year but didn't continue, I wish we had as I don't want to feel any regrets like yourself that I didn't give it all to save my M.
Doing a lot of GAL activities with my Ds, friends and family (and I think H has noticed) its what's keeping me distracted from the emptiness I currently feel.
Keep posting hopefully we can support each other to get through this.
