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

So I sent a letter confessing my regret and love to the girl I have been in love with for the past 5 years. I acted on feelings I developed and ruined our friendship. We haven't spoken since and it has been gnawing a me ever since then. I don't have some grand fantasy that it will sweep her off her feet, and we'll be together but I needed to tell her. We stopped talking because he friends told me she never wanted to talk to me ever again. She never told me her self, she just stopped initiating conversations. 

And despite what it may look like after the fact, there was at least initially some signs of attraction there. When it came becoming friends at first it was her making all the advances and the flirting on both our parts was blatant and in the middle of class to the point were we were told to stop multiple times by friends and teachers.

We started texting and IMing a lot eventually without noticing it I guess I started to initiate conversations more than here, but it was still fairly even. 

She had a boyfriend just broken up with a boyfriend when we started, ended up back together with him for a few months and then broke up with him and we continued.

I guess my question is did I do the right thing sending the letter now? any thoughts on what could have gone so wrong? I'll answer any questions as best as I able.
<bot>: Fell in love with a friend in high school, loved her since then, things ended badly and I decided to send her a letter confessing my sorrows, regrets, and love.
