Need some advice if possible.

Okay, here's the situation...-hope you're prepared- :cool:

There's this girl I like(let's say...Tiffany). I have already told her how much I like her and wanted to see if our relationship can progress into a dating one.(this wasn't too long ago) However, she replied that she doesn't. I respect her reply and don't mind it. But the way she acts now makes it really complicated for me and confusing.

I've talked to her friends whom i know well also. Most of them tell me "Don't". Basically, don't waste my time and move on and don't like her. They would tell me that she is not interested. But...they have no idea, the stuff Tiffany says makes it sound like she is interested. It may just be all my imagination...but i feel like I should still "stick around" and continue talking even though it is surprisingly hard because of my feelings for her.

Here's some background information. Tiffany is the "really social" type of girl. She likes to talk in class and always is talking... I suppose, the flirty type also. She is really casual with a lot of the guys. She is really intelligent, but seems like she doesn't know what she is doing to me even though she supposedly does.

The stuff she says to me are always making me think. She would always message me first. She would tell me how bored she is and whatnot. I mean, it may just seem like she is really just bored...but dang, she must be bored all the time. O.O haha. My older sis told me that a girl really thinks about messaging first to the guy and it may seem Tiffany may like me. But, I don't really want to think of it that way. Tiffany messages me all the time even after my/her friends told her she should stop. This is why i am confused. We would talk all the time about stuff. It's just weird and i can't really figure her out. I have told her i liked her a while back. But she may think that i don't anymore. BUT, you know...she knows i "did" like her and she continues to keep talking with me.

I try to keep it down-low when i talk with her because i can get...umm "too caring" and "involved" i guess. I would really appreciate it if anyone can help me out here because i am getting really...uhh, annoyed. lol
Additionally, Tiffany tells me things that are not really things "friends" would normally talk about. You know...it would be stuff that a "best friend" or a couple would talk about.

What's for better or worse, her locker is even close to mine and of course we have some classes together. So i would always be bumping into her, and thus, making me feel really awkward being around her and talking. I feel that it's just all me wanting this so bad that i am considering that something can happen.

Thanks for your time in reading this and really appreciate and am grateful if you would reply.

p.s- Just a thought, but i know it isn't just me that feels this way. When you see people out there who are real jerks and are given those chances. Just really would like it if i am given a chance. A chance to date a person you really like and able to prove yourself. I hate it when i see girls cry because of guys breaking their hearts and treating them with disrespect and no care at all. I would listen to all my friend's relationships and how they are being mistreated. No care at all from their boyfriends and no respect. I just hate it.
Sorry to be so deep and personal but you know... it's something i wanted to say and let out.

Pretty long...lol, my bad :X
So if anyone can give me heads up, thanks a lot.
