I think DB says to TRY something, but then back off -- with grace and good humor -- if it doesn't work. In other words, don't KEEP on doing what isn't working, but if you're getting a positive vibe, TRY something, and if you get rejected just so "OK -- I understand. Your loss, cuz I'm feeling AWESOME today and it would've been GREAT!" (or some such)
Nothing wrong with letting her pursue, but I'd caution you not to do it out of SPITE. If she's opening up to you, and you reject her out of spite and pure PRIDE, I think you will regret it.
