Her actual age has nothing to do with her innocence. I know 50yold women who are as innocent as 16yolds. Good on you for picking up on that, but also bad on you for abusing your PUA power. That's the type of thing that gives PUA's a bad reputation.
Also, bad actions stimulate bad feelings. I know of a number of guys who (deservedly) got their tyres slashed, etc. Walking away from this woman is going to cause more harm than good. She deserves a proper apology.
It is important to take responsibility for the feelings of resentment/bitterness/any other feelings you caused. It's not necessary to draw out the apology, but you have to state exactly what it is that you regret, and ask her forgiveness. That means you DHV and leave it up to her to forgive you. Thank her if she does, and forget about it if she doesn't. And don't abuse your power again. It's uncool and it will bite you in the back when you least expect it. Here's a good site on "how to apologise". <
