KenM,
There is something about us Aspies that we attract a more than average share of predatory people in our lives than NT's and that woman seems to be just another example. I speak as another Aspie who has had and broken off other relationships more or less like the one you talk about on this thread. I think you did yourself a big favor breaking off and I'm sure you will continue to do yourself favors by standing firm in your decision that it's over.
The impression I have is that she was getting some need fulfilled for herself at your expense and that she never intended to reciprocate, let alone share her life. To me, her antics read as those of a c*** teaser and to add to that, I don't think she's been honest with you during all the time you had together.
You were honest with her in telling her squarely you have trouble reading people and that she needs to be more direct with you. Instead of seeing you in a new light of understanding and acceptance, she kept on playing that sexual cat-and-mouse game as if deliberately playing on your vulnerability. The feelings I have for a person of such caliber are unmentionable here
Oh... And there is that thingy with the wacky tobacky. Having no better control of its use -like any other intoxicant, raises BIG red flags in my book. There is no question that she has a problem with an addiction and only SHE can take the initiative to deal with it.
I know you invested a lot of your energy in trying to see this relationship become something you'd like it to have been and it will take some time to get over the hurt, but all I can say here is to chalk it up to another learning experience.
