I read what you said about what you have in common. The way you put it, it sounds like you were completing each other. And indeed very many couples live happily ever after with this kind of compatibility. There is a But there though. Both partners should feel what they offer in the R is equally appreciated and are happy with the "settlement". Was it so in your case? Did the kids change the balance? I could go talking forever about my H and myself but it wouldn't give you any kind of help, we are definitely NOT a success story...
I am really with ann on what she said about what could be going on in her head during the blow ups she has with you.
