Why isnt this easy.

This is should be easier. I feel like I'm a trapped animal and that makes me furious. Ok I need to start from the beginning. See I'm a preety soft spoken nice guy I do what I need to have fun and relaxe whenever possible. Now that hasn't always lead to good relationships. But last school year that changed. I seemingly finally found the coolest.girl on the planet. Chill as can be with a soft smile and makes my insides flutter for some reason everytime I see her. Now last year her and I began a fling togther it was small and barely anything but still I sorta devoloped a crush on her. This next part is hard to say. Over our long summer vacation things when bad. Lost contact with her then lost her to another guy. Now I new it was gonna happen and I sorta accepted that besides she wasn't my girlfriend and I am not the kinda guy to be so restricting. I just want a chill relationship is all. So summer passed school starts. Horrible first couple of days. Don't know anybody all my friends became ninjas and completely vanished from the school (metaphorically). I go three days without any sign of anything good happening. Then suddenly one day I get a notice. I have no 6th class. Now typically I would have said sweet and just high tailed me ass outta school but that day something made me go to the office to check it out. Unfortunately I was signed a new class which I had to now check into mid week with a brand new teacher that after a few casual conversations. With some friends I found out my new teacher is a complete and total hard ass. Not looking like the best week for our hero but here is where it gets intresting. I. Walk into the new class and low and behold guess who walks in no more than a few secounds later. The girl! she sees me hugs me and we sit next to each other talking most of the class. Lucky right? It got better from there I whent home and about an hour into being home I get a call from her telling me we should try going out sometime because she was thinking about me the. Whole summer. That was also when I found out about the guy. But that didn't matter because she didn't like the guy I though she liked me. Well first time we met up was awesome this time not so much this whole week has been a big downer when it came to her. I look at her with happy eyes and it seems she looks at me with boredom I kinda feel like a toy to her and it sucks. Let me tell you what happend the secound time. The secound time we tried to meet up at a mall just to chill and relaxe well upon arriving there she start kinda acting pissy and pushy. Uncomfortable. She said she wanted to chill because she though I was what she needed in her life a nice guy. But I'm starting to feel used. She ditched me that secound time and I am apparently supposed to chill with her tommarow. (Her idea) I'm not expecting her to follow through. Something just doesn't seem right. What do you guys think. Am I over reacting
