Actually bro yy0202, I say you do stand a chance.
It is common for friends, even closer ones to develop a double relationship 'online' and 'offline'. The reason for so is becos we now use more electronic non-verbal channels to communicate. For example, when we have restricted space for personal relationships to form in our work place, we use sms or msn to chat about non-work related topics with the same colleague.
Problem is, some of us can't read non verbal message very well, have insecurity in facing real relationships or simply can't talk very well. So we tend to rely on non-verbal communication to form another relationship with that person.
My take is, you formed such relationship right from the start and it has got ahead of you. When you come back to real life, your expectations for that closeness is higher. Seeing that she din respond to you as she did in smses, you can get easily confused. It is this confusion that is giving you stress.
To bring it to the next level, I guess you got to breach your own insecurity. She may be trying to get into you too but man you have to take the first move right. If you ask her what is the ultimate end to this, of cos she will say friendship la. Dun expect her to cheapen herself by saying oh I guess I will have to marry you.
Ask her a direct question, something like, if I really want to be your bf, am I on the correct path? Or I really like you, can we start dating? From what I know about pinoys they tend to be more open, so you can just say it out and even if she says lets just be friends, you can actually get a friend rather to be a embarrassed failed suitor everytime you see her.
Bro, save yourself, pop the question. You'll be surprised.
