<human>: Can you provide a brief overview of the text?

Back-story: We had some differences on certain habits. Since the beginning of our relationship I told her I didn't like women who smoked, I found it quite unattractive. At the end of our relationship she went into this rebel phase where she started smoking and clearly didn't care about my opinion. We broke up and she confessed she "flirted" with some other girl during this period. She told me it lasted for a week nothing ever happened other than that, but the thing is that this other girl became a good friend of hers.

Present day: She felt very sorry for everything she had done and she wanted to get back together. I agreed and told her that we had to work on things. I told her I felt very insecure about her friend and she assured me that there was nothing going on. (I have a a history for dating people who cheat on me so I kinda have major trust issues.) I told her to take things slow because I was kinda hurt with all that had happened. The day we get back together she tells me that THAT friend was staying over at her house that night. I didn't mention anything about it. My mistake. During the day I told her to call me and I never received a call. She told me that they had something to eat and that she felt uneasy and that she went to sleep. This is the point where I told her that I didn't like that her friend was staying over her house with the history they had and so close to our getting back together. She told me that she didn't intend to change who she was or what she did. Was it wrong of me to ask this of her?
