Great advice guys...in fact, two lady friends whom I trust told me almost exactly the same thing. I'm on it.
On the question...let's just say her attraction was clearly demonstrated.

Now, there is one issue that I still have to contend with and that is her exBF. We're in the same meetup group, so he's around, and in fact he and her are still friends (amicable breakups are a good thing, IMO). She wants to call us "just friends", and I think the main motivation is that we are in this same group. I'm seriously considering dropping out of the group for a while if it takes a roadblock out of the way. I'm not jealous of him (he seems like a good fella, but I think I have him beat by a long shot...I've learned that he's an alcoholic, and I suspect that's the reason for the breakup). However, she feels very weirded-out when the three of us end up at the same social event. She's said she knows he and her are "not meant to be", she wants to comletely detach, but it's like telling your best friend good-bye. Again, an amicable breakup is good, but it does leave some loose ends to tidy up. So, I don't think she's 100% "emotionally available" yet...but, I think that will come in time. For instance, she chats with me just about every single day. I just need to keep her engaged and as said above "make her feel special".
We're going to dinner and a comedy club tonight (and she's investing in the relationship too...I bought our tickets, she's buying me dinner and drinks). This should be a great opportunity for some good one-on-one time.
