<human>: Provide a brief overview of the text.

I've been hanging out with a girl who went to school with me. She graduated, but we still see each other often (her company is affiliated with my school) I told her I really liked her and she said that she liked me as well and would want to date. She also, however, said that it would be awkward because my sister and her are really close and she's friends with an ex.

I decided that it would be a good idea to keep spending 1-on-1 time with her. That may not have been the best idea, but it's too late to change it now. 

Fast forward one month and we are seeing each other a lot. I just got back from a two-week trip and we were texting a lot. I think we get along really well. I invited her to go see a concert on Valentine's Day and she said that she would like to come. I'm not sure if she's just being a nice person or what. 

Does anyone have any advice on how to proceed? I'm pretty new at this dating thing, only had one other girlfriend and that didn't go so well.
<bot>: Really like a girl, I may be deep in the "friend zone" or I may not- I'm pretty confused and looking for some help.
