<human>: Give me the gist of the text in a nutshell

Hello, all.
So, I met this girl early in my freshman year at college. We lived on the same floor of our dorm and as a result, saw each other often. About halfway through the year, we started to chill together a lot: going on walks, staying up all night and talking, etc. I really fell crazy in love with this girl. She occupies what seems like every thought that passes my mind, and I've had many sleepless nights thinking about her too. When the school year ended, we went our separate ways for the summer. We live on oposite sides of the country, so we weren't able to see each other until the following fall, but we would text constantly and skype from time to time. This last school year, we both had apartments and so I saw her rather infrequently, but I was (and am) still crazy about her. Ever since I'd met her, she had this boyfriend back home (I know, classic, right?) whom I always thought was kind of a dick. It seemed like they fought more than they were happy, and I remember many times when she would be sad after a phone call from him. It killed me to watch all of this, because I care about her so much and I know that she deserves more. She recently found out that not only is he now seeing someone else, but he was cheating on her for a long time. She was understandably broken up about it for a while, but is now doing better. And now we come to the hard part. I've wanted to tell her how I feel for so long, but I am just terrified that I will ruin our friendship. At the same time, I recognize that I have probably been friendzoned real hard. What do you think I should do? Should I tell her? How would I go about doing so?
Thanks
<bot>: Been in love with a girl who just recently broke up with her (cheating) ex. Also, I feel like I've been super friendzoned.
