The Awkward Moment When The Guy You Like Thinks Your Taken

      A few years back my best friend gave me a necklace.  It had flowers and hearts on it, and when you open it it reads " Girlfriends are the family we pick for ourselves."  She gave it to me for being such a great friend. I mentioned how it was actually supposed to be for a boyfriend to give to his girlfriend, she didn't think it did at all.  I felt bad not wearing it because it was real silver, she spent a lot of money on it, and she was so happy when she gave it to me.  So I wore it, what do I care, it was in small letters anyway so you would have to be close to even read it, plus it was covered by another layer of silver.
       Now that you know the back story lets fast forward to today.  The guy I like is in my cooking class, and since we sat next to each other we got paired into the same group.  There are two girls and two guys in every group.  Me and Zack, the guy I like, usually get along so we decided to make the cookie dough and let the other members in our group to do the cookie cutting and decorating.  While we were rolling out the dough he kept throwing flour at me, I pushed him away and he saw my necklace.  The cover plate of the necklace must have moved because he saw the words.
he asked "What does your necklace say?"
oh crap.....
" oh, um it says girlfriends are the family we pick for ourselves"
"oh, that's cool..... its crazy they can fit all those words on a small necklace, right? haha"
"um, yeah I guess, that is pretty crazy."

    That is when he packed off and was distant the rest of class.  So just so it doesn't happen to you, don't wear things, or say things that make it seem like you're taken, because the good guys that may like you will back off. So once again I found another way to mess things up.  I still will wear the necklace, I grew to like it too much, and now that my best friend has moved away its one of the only things I have left of her.  Now I have to do damage control, I should have told him right then and there but I didn't want it to seem like I liked him, but now I feel like its to late to say anything, so I'll just let it go, and see what happens.

This is what the necklace looks like.

Has anyone else had this happen to them? Liked someone who thought you were taken?
