Holy crap, I'm out of the friend zone with a previous oneitis. How do I not screw this up?

This girl (31) and I (22) have been friends for awhile and just recently confessed we're into each other. I asked her out before but she had some ex issues. I stayed friends with her because we have a lot of the same interests.

Well, the ex went out of the picture a few months ago, and now it seems I have another shot with this girl. It seems she is hesitant in starting something with me, but she was okay with the idea of going out together sometime. I'm not really sure what this resistance means and how I can overcome it. I don't want to lose this attraction I have with this girl and get LJBFs. I assertively asked her out and she said yes, hopefully she won't flake.

How do I not screw this up? I don't want to be an AFC since feels like I'm gonna have to push for what I want. What things can I do next time I see her that could make her give in to her attraction?
