I feel us turning into roommates.

my wife and I are in our early 30s. One child. wWe've been together since high school. There's been ups and downs like any relationship but this feels worse. Maybe this is naive but I feel like id rather be fighting that this...nothing. Idk how to describe it. We are nice to each other but we rarely touch. Im not talking sex either, hand holding, even putting my arm around her has gotten so rare. I'm sure im contributing but from my perspective shes just pushing me away or jerking away from me, as if just brushing up against me is unpleasant. We still have sex once a week but I feel like a chore to her. She outright told me she doesn't get horny any more

fuck sex though i fantasize about cuddling on the courch again. I dont know what to do. I told her and she basically just changed the subject. I dont want to leave her as I do love her very much and would probably just be alone if I wasn't with her, but i feel like its not even an option as Im the sole income.

is it possible to tell if there's still any spark left I could rekindle or am I holding out hope for something impossible?
