I NEED HELP!

Remember the guy I told you about in my other blog Girl Talk? 

Well it's actually a long story but to cut it short, he confessed to me on the day we started texting, one friday, when we were the only ones left in school, he sang All of Me to me while playing a guitar and that made things freaking awkward that I can't even talk to him, so I kind of kept myself away from him! Then during our school camp, a 4th year dude that's like a brother to me since he helps me out with these kind of things, confessed that he liked me even before we started talking and that made things awkward for us too and we don't talk as much as before as well! Then one day, the other dude(not the 4th year) gave me a letter saying he's sorry that he made my life complicated and that he'd try to forget everything but he's doing that because he loves me and I swear it made me feel so uncomfortable like "Hey dude why the heck are you saying this? Fyi, there was never an 'us'. You're acting like there was!" And now, he's saying that I should just forget about the letter because he can't take it anymore.. Just when I finally got over him he does that.. But the problem now is... I think I'm starting to like his best friend that my best friend likes at the moment.

I feel so confused! What should I do?
