Oh classietgal, I really feel for you.
It must feel like a no win situation for you.
I imagine you have been placating this man child forever. Want's his own way, doesn't get it sulks, silent tratment, ignors you and then when you can't stand it any longer, know you have to swallow your pride and cajole him into making up'
Fucking exhausting, demoralising and soul sucking behaviour that tramples any feelings of self worth.
He doesn't get it, never will because his feelings are more important than yours.
A long time together and you are learning to stand your ground more, you are hardened by it all, you are not sleeping together.
The lines have been drawn in the marriage.
I will say it is at this point in marriages like these, one partner actively finds another to proove they are capable of love, its usually the man.
Could you go to councelling together, it sounds as though he needs educating about his behaviors, he won't listen to you.
Banging your head against a brick wall comes to mind.
Some men are emotionally stupid and he sounds like one of them.
Take care
Maybe I'm totally wrong but thats how it reads to me.
If you want to save the marriage don't let the resentment build up any further, you will get to a point where it can't be saved.
