Yes. 2 of my crushes know that I like them.
This just happened on Wednesday or Thursday, last week:
I wanted to tell my friend who my new crush was and I knew I could trust her. She promised not to tell anybody. So I told her (this was in math class). Yup. And then she writes it on the persons math book who sits next to her and all over his paper. "Jamie <3's C" (of course, she wrote the whole first name) I got really mad at her for that. The kid who she sits next to and who she just wrote on his stuff, lets call him T. T went up to the person I like, and we will call him C. She said "I know someone who likes you". T's friend, L, over heard him and wanted to know who. So he asked and he wouldn't tell him. He guessed it right after a while and he said that was right and not to tell. So L goes up to C and says "It's Jamie who likes you". Great. Now he knows. This can't get any worse... but it does. Without asking me if it was okay, he goes up to C and says "Wanna go out with Jamie?" C said "No way! Eww! I would never go out with her!". This all got to me. My friend thinks some really popular kid in my grade knows, too.
I really just wanted to stay as friends with C, and not go out with him. We are friends, but not close.
And last year in 6th grade, my friend told the other person I like that I like him. So as of last week, both of them know, and both of them are my friends.
Also, last night, I was on aim and I told the other guy I like, D, who I liked. I told him there was still one more person (which was him) but I wasn't going to tell him that, maybe he forgot!
And sorry. It has happened to me before, so I know how it feels.
