Xenia, I just read your post about 'giving it' to my dp. He said he would prefer not to have sex than have it because I 'gave' him it.
To the OP, I'm not sure what to advise, but there are a million and one ways to make a woman feel sexy, IMO, make her feel special, appreciated, and above all the love of your life, where sex isn't important.
Try things slowly, work on touching her, not sexually, just a hand on her hip, or a ruffle of her hair, somethiing that makes you get closer. When you feel she is accepting of that try a little more, a hug, a kiss on the cheek, keep doing it til she responds (not daily but over a decent period of time) and each time take it that little bit further (tiny baby steps here).
Treat her, cook her a meal (romantic meals IME are much better at home cooked by the man you love) do all the things you would hope to lead to sex, but without ever mentioning or even thinking (us women are mindreaders) about whether or not it leads to sex.
From what you have said you need to get the intimacy back first, and it has taken eight years to get to this point, could take another to get back to how you were.
Sometimes, we are extremely tired and sex is the last thing on our minds, then we notice that our partners are so desperate for it that every attempt at physical interaction is like a cue for sex, so we become further and further apart, each attempt at a hug feeling like pressure to have sex if this isn't dealt with, you end up with a situation like you are in now, a form of stalemate.
Your dw needs to know that you can have intimacy without any form of sexual interaction, the better that ets the more likely it is you could, one day, rekindle your sex life.
Lastly, this isn't yur fault, nor is it hers, it means nothing about how much you are in love. It just means you need to relearn how to be lovers.
