Ok guys I need your help. PLEASE!!!

I really want to see how guys reply to this cause it may infulence what I choose to do in the future...so if you could take the time to help me with this and speak as honestly as you can I would be very apreciative.

Ok to to this you will have to:
Imagine you are a boy (Should not be to hard)
About sixteen/seventeen, you have been told by people that a girl likes you and I mean REALLY likes you and has for three years. But she aint that special, has never held an actual conversation with you and you have had a gf for six months.

Right now I want to tell me how you think you would react to these situations:

1. If the girl who fancied you, made an attempt to start a conversation with you for the first time in three years. Acting only in an airy, off hand way.
OR/AND if
2. If you saw her one day crying, looking completely heartbroken (Ex: would you approach her? Say anything to her? Run like hell?).
OR/AND if
3 She just approached you one day and told you point blank she loved you. (Would you refuse to talk to her after that, try to be friends only? What?).

Something else (just extra)
Also (Incase you had not guessed-Im the girl that has fancied this dude for three years) this boy im asking you to imagine to be...well we met eyes and smiled a few days ago and I realised what I was doing and ran off into the nearest shop...but he followed, he did not come to near though or try to talk to me and when I went out he hung around for a bit...so im confused, maybe he just likes the idea of having a girl fancy him, but, I dunno...guess I should not get my hopes up...easier said than done.

Anyway if you could answer the three questions as truthfully as pos and if you have any input about the latter matter then input it-PLEASE! Thanx so much...it means allot. Girls you could to if you want, for fun...if your that bored lol...

1) I fail to understand "Acting only in an airy, off hand way."...Well..I would talk to her, i suppose

2)I'd approach her and ask her what was wrong, and try to comfort her, whether she told me what she cried about or not...

3)I wouldn't refuse to talk to her, I'd tell her things the way they were, and why I couldn't get involved with her...

Airy, off hand-Umm...sort of like a "nice weather we are having isnt it?" kind of way...
Thanks tho.
Anyone else know what they would do?

*echo*anyone?*echo* Please...

Well I have waited three years and hoped he would talk to me but...I dunno, knowing me I probably will continue to wait...but the thing is I only have a year of school left and if he leaves before we talk then I will never forgive myself...nice poem tho, very sad. X
