I think that if you stick to doing what you would do for a friend, not the best friend that you might get arrested for, just the guy from work, common courtesy kind of stuff. I think that if you think that you are doing it to try to make her see what a good guy you are, Dont Do It! Sandis Do/Dont List on page 1 of your thread has some good stuff in it.
I do have to say that you going dim seems to have worked, its good that she is initiating contact.
I guess I gave the wrong finger to the wrong man...
