<human>: Okay, I am super confused by this girl. I have known of her for over 2 years because my little sister has wanted me to date her for that long. Problem was, I didn't really know her or how cool she was until I met her today. About a year after my little sister told me about her, she got a boyfriend, and I wasn't really interested because I was getting ready to leave for university. Well now that I know more about her, she is driving me mad. I want to take her on a date, but she is caught up with her douche boyfriend. He is, in all aspects, a douche. The only reason they are still together is because he is good looking, so they are breaking up this fall when she goes to college (my little sister told me). She likes me enough that she said she would go out with me over Christmas break, but I really just want to date her now. I don't see why they are still dating--he treats her like dirt. Which brings me to my dilemma: I ran into her today and she invited my sister and I over for dinner. As dinner got closer, she told my sister to come over but for me to wait until my sister texted me to come over. Later my sister texted me and told me they are talking about her boyfriend. But she said I could still come over. My question is should I still go over or should I wait until a better time? I really like this girl and I need some help!

Can you condense the text into a few key points?
<bot>: got invited to go to a hang out with a girl I want to date; has a boyfriend, and I'm not sure how sincere it was.
