She sounds quite manipulative, and the concert thing, she is playing you like a yo-yo, pulling when she feels like it, pushing when she feels like it. She sure sounds like she is acting like a 2 year old who wants everything to be her way, if not, she will pout.
About the gift, DO NOT GET HER THE PURSE, I would probably get her a gift, something nice, at a lower budget. What have you historically spent on her BD gifts?
About the car, I would NOT let her drive the car at all. Not for a while and without any condition attached to the "drive". The first step (Not for a while yet), could be for you and her to go on a nice drive TOGETHER in the car with you driving, then maybe let her drive TOGETHER. I would not in any case or reason lend her the car without you in it.
Lastly, on the S15'c comments to W, GREAT! The more people tell your W that she is acting like a child, the better; I think. I would not fuel his fire, but would surely not reprimand for calling her out!
Good luck.
