I think I know where you’re coming from; and my children go to bed early, so I don’t see that as the root cause of all your problems.
My husband is lovely, kind, does a decent share of the childcare and housework...I’m told how lucky I am to have him. He is the stabilising influence to my emotional extremes.
We have never had an argument because he would shut down completely. I grew up with 3 siblings and arguements were the non-threatening norm. Now my only option is to bottle things up, but can’t always keep it in, meaning from time to time I come across as a passive-aggressive shrew, and subsequently hate myself.
He cycles, which is his passion, and although I do too we never go out together as I half kill myself to keep up with what he considers to be a slow dawdle. Our summer holiday is one the kids will love, but it will be me having a fantastic time with them, throwing myself into the stuff they love while he is there on sufferance, only really having fun when he’s off on his bike in the mountains. When we go on family walks he strides ahead, while the kids and I walk behind, chatting and tree climbing and cloud spotting. And the children are just teenagers now, so it’s not like having to entertain toddlers.
So yeah, I think I know how you feel, I’ve been unhappy for years, but ‘never having arguements and failure to enjoy himself on the beach’ doesn’t really give grounds to break up a marriage, so we plod on. Sorry, not much help to you.
