<human>: Can you provide a brief rundown of the text in within 3 sentences?

So, we start 2 weeks ago when I told this girl I liked her a little bit, she was all AWW and what not. Now to yesterday, she asks me to go down town with her because she wanted to go shopping, I obviously say yes because I wanted to spend time with her. When we're down there she's wanting to hold my hand and what not which I was completely fine with. Later that night I started talking about if she was liking me or anything, and she tells me she has a boyfriend... I was shocked because what I usually think when someone is dating someone else you don't hold hands with someone else, especially after they tell you they like you. I asked her why she would do it, and she said it isn't a big deal to her or her boyfriend if we held hands and started asking me why it is such a big deal to me. Am I in the wrong or is she, because she is pretty adamant about it not being a big deal.
<bot>: I went down town with a girl who I liked, we held hands then she tells me she has a boyfriend and says it isn't a big deal to her or a boyfriend, so why should it be one to me.
