Read all replies and it put me in a sad mood so I might as well share a story.
I met this girl about a year ago and we became pretty good friends right away. I liked this girl quite a lot but she had a boyfriend so I never said or did anything to show her my feelings. I'd talk to her just about everyday and we became really close friends and talked constantly for about a month. Then one day she tells me she broke up with her bf, and of course this made me a little happy but I didn't talk to her any different at first, I still hid my feelings. We still spoke everyday and about a week after her breakup she started flirting with me, and I began flirting back and eventually told her how I felt. This went on for a week, maybe two, and then she told me "I think I'm in love with you" and I honestly felt the same, I thought she was the one so i told her. We continued talking for maybe a week, and the whole time I was falling for her more and more. Then one day she just stopped talking to me completely and I find out she got back with her ex. This was the first girl I ever liked and the only person who has ever liked me, or at least said they did. Shit fucked me up for a good month or two.
Then after about two or three months, right when I got over her, she started talking to me like nothing happened, as if we were still friend. She's still with her bf and we continue to talk, as friends, every once in a while, and it honestly depresses me everytime we speak because I still have feelings for her and she doesn't, or at least acts, as if she doesn't and never did.
