I'm really down in the dumps. I have no clue what to do. :( Please help!?

Let's title 3 guys- Joe, Bob, and Daniel.

I had liked this guy Joe for quite awhile. He ALWAYS flirted with me and we were neighbors and good friends. When the opportunity came around that we could be together, he told a good friend of mine that he was going to ask me out on a date. He also liked 2 other girls. He was going to ask the 3 of us out on casual dates and decide what to do.

Then he stopped liking me. I was really kind of hurt. A few days later, Bob asked me out on a date. He was a nice guy who I'd never given much thought to. The movie went well, and then he asked me out again that weekend. We had a really good time! He said he wanted to go out on another date.

Then about 2 weeks later he just stopped talking to me. When I saw him he wouldn't even say hi. I was starting to wonder what was wrong with me.

Then Daniel came along. He had been my good friend for about a year. His brother is also one of my good friends.

Daniel asked me to hang out on new years eve.

He even wanted to go to a park with me a lay out a blanket. We hung out again after the first time and had a really good time. We recently hung out AGAIN and his brother said he had been planning on asking me out... but was nervous. But he also said he doesn't "like me much and only sees us as friends".

His brother has been kind of dramatic before. Should I trust these things?? I want to talk to him (Daniel) but I'm nervous about it...

IS there something wrong with me? I hear that I'm a pretty and funny girl.

I'm getting really hurt :( I'm always kind to others. why do i deserve this?? any opinions?? thanks.

oh, I'm 15 by the way. Joe is 16 and Bob and Daniel are 17.
