So quick story short, I was really close with this girl and I developed some really strong feelings for her, I fucked up I know. I thought things were going really well but I found out today that she started seeing this other dude, that had a thing with her half a year back. My problem is that I don't usually like a lot of girls, and I did actually like her, so I kinda got her on a pedestal, which again is a fuck up. Any advice is welcome.How the hell do you deal with these feelings? I'm trying not to think about it, but I can't. I'm 20, haven't lived life yet, and I don't know how to deal with this.
