<human>: She has been trying to break into the restaurant mgmt industry and went to lunch with a single restaurant owner / operator. They ended up going to a very high end sushi restaurant, ate/drank and he paid for it all. There is no position open it was just to talk about good. I also find out they have been texting a ton. Once again the majority of it being about food. But I definitely feel like she has crossed the line. She also won't let me read the texts because it would invade her privacy. I told her it was very inappropriate and I am going to break up with her. She said she did nothing wrong. What are your thoughts?

Could you distill the essence of the text into 1-3 sentences?
<bot>: GF went to a "networking" lunch with a restaurant owner where they ate/drank and he paid for it all. They text all the time and she won't show me them. Should I break up with her?
