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

I have a girl that I have known for almost four years and we are friends. Woman? Beautiful woman. Absolutely amazing. She is the sweetest and a ray of sunshine. Makes everyone around her happier and much better. Very extroverted, but has a thoughtful side that I don't think people take much notice of. As for myself, I tend to be quieter and a listener, but -I- think I have a great sense of humor. Took her out on two dates essentially, once to a city about 90 mins away and the other to a nice Italian restaurant. Both times prior she seemed to be into it, but both times afterwards she said she would rather just be friends. The last date happened about a year and a half ago. But she seems to be coming around again and I have always been really into her. Should I try to go for it again, or is it one of those "you can't make people love you, either you do or don't" situations? We were both younger and less mature before, and for myself I can say that I have matured pretty significantly since two years ago. In the meantime she has went on a few dates with various guys and was in one relationship. My general feeling is that I should tell her how I feel, but it has to be obvious to her. Also to note, she is one of the few I get nervous for, so I know that I am into her. Feel free to ask questions, I'll give answers.
<bot>: Unsuccessful a couple times with someone I like, but she possibly is coming around again. Go for it or let it go?
