Close friend and I mutually confessed to each other but she might not what to date. What should I do?

I (22 m) really like this girl (31 f), but I was friend zoned last spring by her. She was single but she had some ex issues. I decided I was content with friendship, and we have become good friends.

Anyway, she is finally single and over her ex. Recently we have been talking about what happened earlier this year and it pretty much evolved to us admitting we're interested in each other. However she isn't sure she is ready for someone else. I did get her to agree to go out on a date soon but I'm scared she might get scared and flake.

I'm at a lost what I should do. We really like each other but she doesn't think she is ready. I want something now, but I don't want to ruin the attraction between us. What can I do to get her to change her mind? I really don't want to fuck up this potential second chance with this girl.
