Am I in the wrong?

I have been dating a woman that is 9 years older than me. She works with Visiting Angels. She assists a man in his 80s with Alzheimer's. He was having a good day and wanted to get out of the house and go to an Italian restaurant. He owns 4 vehicles, one of which is a Porsche that doesn't have a current tag. My girlfriend texted me a pic of tiramisu saying that one was better than the one I took her for at Olive Garden. She likes the food there and I really like the tiramisu there. We exchanged a couple texts about where she was and then she sent this:
"I got wined and dined by a multi millionaire with out the wine and had a wonderful time! He's doing better today".
We have a phone conversation where she tells me about all 4 of his vehicles, that it's a 4 door Porsche, she's never seen a 4 door Porsche before, that if the tag had been current on it she would have been allowed to drive them to dinner in it, and how she will drive that Porsche before she stops working for this man.
Eventually I tell her that I am insulted that she would gush to me about her clients vehicles and how he made her feel like a princess since I have paid for every date we have been on, I bought her scrubs for her to wear to work, I buy her things for her house, and she has never said anything about how nice it is that I treat her so well.
