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

First off, it's late and I'm on mobile, so please forgive grammar and spelling errors. Second off, I didn't know where I should post this, but here seems like the best place. 

I really care about a girl in my life. She is sweet and charming and a huge nerd. We've known each other for a couple years, and I care about her deeply. I've seen her go through breakups with assholes, and when I see her sad, I'm sad too. 

Now I've only recently come to see her as more than a friend, only around a few months ago. I realized that I might love her. I know it sounds fucking creepy, but I think I do. I care about her, first and foremost. I just feel awful because I desperately want to be with her, but I know that she would be happier with someone else. I want to be with her, but I want her to be happy 

I know this isn't as serious as many other things on this subreddit, but I don't know what to do. 

Only a few minutes ago I told her how I feel, and she said we wouldn't be right for each other. I responded, telling her I'm sorry for straining our friendship, but she hasn't responded. I'm hoping she fell asleep and hasn't read it yet. I'm so nervous and confused and sad and fucking angry! I don't even know why! I would just love if someone had any advice to give me.
<bot>: I think I love a great friend and told her. She said we weren't right for each other. Now I feel awful
