Personally, I would get together with her, but be completely honest with her and with yourself about where you are in your life.
I've been out with a couple of old girl friends lately (that's old friends that are girls, not former girlfriends) that I had lost touch with. Absolutely platonic...on my end at any rate; not sure what their motives were/are, but it doesn't matter. I let them know what's going on with me, just so there's no uncertainty. Had a great time, and they're both people who genuinely like me and are concerned about what I'm going through, so now I've got a couple more friends to help pick me up and dust me off when I'm having a hard time doing it myself.
