Assuming that you are entirely genuine and not some reporter looking for a story, I will tell you this:
I could be your DW. I am not, but I could be. I have no libido, I don't really like DH touching me affectionately, I repulse him most of the time.
I feel sorry for him that I do it, but not enough to stop doing it. I don't find him physically repulsive at all, I am just not "in the mood".
He is not very good at sex though, so I don't find it particularly pleasurable - and that is hard. It's all very well saying "I want to give my wife pleasure" but you have to understand that if she doesn't want to have sex then any sex is not really going to be fun for her. For starters, lubrication is an issue - not being turned on means that we don't produce any lube naturally. For second, anything that isn't quite right becomes much more wrong and puts me off more. My DH and I have sex most months but only because we are trying to have another baby - he has said before that if I get pg again, that will probably be the end of our sex life. HE might be right, although I hope that I wouldn't be that unkind to him.
Every now and then, I do give him a hug - but sometimes when he wants one he doesn't get it - because he tells me that I look like I need a hug. No. I don't.
He asks for a foot rub in the evening - but he has done nothing to help me all day (except go to work to earn money for us all, of course, but that's a bit abstract in the daily grind of life with a toddler). My DH is not a giving sort of person - he admits this freely (which helps) - he agrees that he is a "taker", but makes no effort to change this. He bitches and moans about having to share the cooking and washing up duties and can be unbelievably petty about whose turn it is - because God forbid he might end up doing me a favour by doing an extra turn by accident.
I resent a lot of my DH's behaviour - he irritates me something rotten sometimes! - and that doesn't incline me to want to be physically intimate with him. I know some people find that certain emotional states, like distress and anger, can make them feel like having sex - not me. I have to feel loving and loved and, probably more to the point, cared about. I know DH loves me but I don't often feel that he cares about me, can you see the difference?
But this is my situation, not yours. I'm sharing it from my POV in case you recognise any aspects of my DH in yourself. If you don't, or choose not to, then this post will be of no use to you whatsoever.
