I'm 27 and she's 38. HELP

So I made contact with this gal last week and we’ve had 3 solid convos on the phone since. We met for the first time tonight at a book store. The coffee shop in the book store was packed so we spent the date strolling around and generating conversation from books and magazines we were interested in and through small talk. I thought it went pretty well and I was in decent control until I hesitated to make my exit and end the date because I thought it would be rude (good ol’ overly considerate and counterproductive me). In hindsight it would have been the right move and at the right time. Instead I held off until she said, “alright dear I’m gonna head home”. Not the words I wanted to hear. I dunno if they were belittling words or just her natural form of vocab. And when I walked her to her car the nervous me who was contemplating her state said, “alright, I guess we’ll talk soon” to end our conversation in which she replied, “ya, just send me a text”. Again, I dunno how to interpret this. She said the same thing the last time I spoke to her after we set up the date on the phone and she is crazy busy with work and work travel so a text does seem reasonable (I may just be trying to work his out in my favor, I dunno). Again, the beginning of the date and middle went well, but it’s the end I’m concerned about. I dunno what her conclusions are. I personally think it went well enough that I am optimistic in having the possibility in setting up a second date. I need help, when and how do I execute this?
It would be useful to know that this petit lady is not only a pretty face, but it was evident she is financially successful considering the brand new beemer she rolled off in when we walked to the parking lot together. I don’t mention this to impress, but to let you guys know where my head’s at. How the fak am I gonna wheel and seal the deal with this attractive, financially successful WOMAN when I am 11 years her junior and a Joe Shmoe?! I haven’t had a date in a month and haven’t been in a relationship in quite some time. I’ve overcome some personal issues and have decided to get back in the mix with intent and thought a good start would be with a coug to have some fun with. It would be worth noting that in our convo she inferred that she is somewhat of a player after she said, “I’m glad I’m not a guy because if I was I would be such a player”. This comment did not detract me, rather, it made me enthusiastic to know that I could be a target of play for this lady. I want to make sure that not only am I a candidate for her pleasure, but a selection. How do I tie down this second date?

Stop your nervous! she is a woman: it's the 1st and the last. The main hing for you is to be polite and natural
