Did she tell you at the moment you gave her a non-sexual touch that she did not want you touching her at all? Was it the same day she rejected you sexually?
If she reacts whenever you barely touch her like you'd touch your grandmother.......she's got some serious issues. How does she react if someone other than you gives a non-sexual touch? That might shed some light, at least knowing if it's just you she doesn't want encounter any physical contact.
Should you try again? I'd still like to hear what you tried, how much/often, etc. It just seems a little odd that the two of you can enjoy each other's company so much, and yet she wants to keep you at an arm's length. You can't think of any emotional need she has that isn't being met? I can't remember if you said she's ever taken that test to determine her love language. Know the one I'm talking about? Words of affirmation, gifts, physical touch, or works of appreciation. We all express and receive love in different ways.
You asked a simple question. So.......unless you can tell me something that might shed more light, I would suggest you not try to touch her if she has clearly told you to keep your hands off. If it doesn't work, don't keep doing it.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
