That's a great sign. Hopefully your giving space helped her have the time to think things over and decide that dates might be a good move. If you look over your posts from a few weeks ago, you probably wouldn't have predicted that dates suggested by W would be in the cards. Celebrate your progress.
Here are my rules for going forward:
1) Don't assume that everything is now ok: W views you like a pent-up dam full of emotion. She's afraid that being nice to you is going to pull the plug and wash her away, and she doesn't want that. Continue to assume that W wants space and don't start talking about reconciliation or R discussions until she starts initiating them.
2) Don't escalate: If she says she had a nice time, don't say ILY. If she holds your hand, don't hug her. If she hugs you, don't kiss her. You can reciprocate, but don't take anything up a notch. Let her lead.
3) Expect hot and cold: Your W will "try on" being nice to you and letting herself believe that everything will be good. Then she'll catch herself, worry, and suddenly go ice cold. Don't take that personally, it's natural and part of the process. Don't comment on it, pretend you didn't notice, just roll with it.
4) Manage your expectations: It's tempting to get hopeful when you start to see positive signs. That hope can create expectations that then lead to disappointment, and that disappointment is very transparent. Expect nothing that you'll go out and be relaxed and try to have fun and that's it.
It can be hard to find neutral things to discuss. My DB coach suggested looking up "conversation starters" before the date so you'll have some interesting topics to get things going if you feel things are slowing down.
