<human>: Can you give me a shortened version of the text?

I'm 21[m] and she's 19[f], and we've known each other since 2007 in High School. We hit it off right away and she was super into me, but I had a girlfriend at the time. I realized I was starting to feel something much stronger for the new girl in my life, and that we were much better together than my current girlfriend and I. I'd been wanting to get out of the relationship with my current girlfriend anyway, but doing so would have very clearly resulted in partial exile from my group of friends at the time. Nowadays I see how stupid it is and how they weren't real "friends", but back then I still had a lot to learn and thought my friends were more important to keep then personal relationships.

Because of fear of losing all my friends I'd been in the group with for so many years (once again, I realize what a mistake this was) I stuck it out with my current girlfriend and broke the heart of the girl I wanted to be with instead. Fast forward through a lot of years of us awkwardly trying to have a friendship where it's very obvious that there are still a lot of feelings on both sides, but I know she doesn't want to let herself trust me.

We've hung out more than ever over winter break, we've been texting all day every day, and I took her to a really special viewpoint last night and talked for hours. It was one of those moments where I felt like I should kiss her, and I probably would have with any other girl, but I'm terrified that if I move forward before she decides to let herself trust me again, I'll shatter the friendship and any chances I had at making it work. 
I care a great deal about this girl, and I really want to be with her.. but for the first time in our lives I can't read her, and I don't know how or when it'll be okay for me to make a move. Does anyone have any advice or have you ever been in a situation where a great deal if history prevented you from moving forward in a way you normally would?
<bot>: I have a great amount of feelings for a girl whose heart I broke 4 years ago, and we were never in a proper relationship. I am hesitant because I feel like our history makes her apprehensive
