That's how I feel right now.

At recess yesterday, I was on the swing and there was three open near me to my left. I noticed my crush and her friends running and shouting "Swings!" Her friends grabbed the 2 farthest away from me, leaving the one next to me open for her. She took the one next to me and my mind became overwhelmed with pleasant emotions

I felt like the happiest guy in the world, with her sitting next to me. I could see her facing towards her other friends and never looking my way, and I was doing the same thing. For something kinda silly, it gave my body the energy it needed to survive school for the rest of the day. I felr like someone could amputate both of my legs and I wouldn't feel a thing. Seriously, I'm was that happy.

That was yesterday, as I said before. THIS is today:

At lunch, two of my friends urged me to once again go talk to my crush. She was sitting with her friends, although she wasn't involved in any of their conversations. I said, "I'll do it, if you guys promise to never, ever ask me to do this again." They said, "OK."

I started walking towards her, but then I thought to myself, "Am I really going to do this?" I was about to turn back when one of my friends pushed me into the seat across from her.

"Uh, hey," I said, blushing. She simply nodded. We both looked away from each other, but then our eyes met again. I now know what it's like when they say 'It felt like we sat there for eternity, staring at each other,' because that's exactly what it felt like. Finally, my crush's friends broke the ice: they walked away. And she did too, saying, "Sorry."

I don't think I should've gone to her. It wasn't apparant to me at first, but then I realized that it was like she was breaking up with me, even though we never talked to each other before, had no previous contact, or anything.

Does anyone have any advice with girls or anything for my situation?
