We went through something similar for about a year. We stopped listening to one another, both got unhappy, and the attraction dwindled.
At first he just wouldn't listen when I said I was unhappy- he took it as a personal affront I think, because all he desperately wanted was for me to be happy, and he couldn't face the fact that he wasn't.
But after one blistering row, and me buying a suitcase, he woke up and started to listen. We worked through a lot of things, both sides, and the attraction came back, first slowly, then massively.
We slept in separate rooms for a few months, so as not to confuse things but prioritised time in the evening, first for cuddling, then for kissing, then for fooling around. And at the same time kept working on listening to one another and getting better at communicating.
The thing is though, there had been attraction there at the beginning. I did genuinely reach the end of my tether. He did honestly have the best of intentions and was just a bit ignorant about how to deal with stuff (and when he finally woke up and realised there was a problem, he did put a lot of himself into working it out and genuinely changing, one step at a time).
A lot of it was that he has very stable parents- still married, spend a lot of time together now they are retired, never fought in front of the kids. So he genuinely didn't have a clue what to do if things didn't stick to that picture- he really subconsciously thought he was doing everything right just by going about marriage like his mum and dad did.
But you'll get nowhere if you never fancied him and if he can't admit that change, by both of you, is necessary.
