Confusing rejection

Before i start, i would like to highlight that she is from Albania (17 close to 18y) and i'm not going to dive into details in respect of her privacy. I am not Albanian by the way (21y), we met during our holidays on a neutral country and we were communicating in English. Her father is the classic traditional Albanian father type that won't let his daughters mess around with anyone ,unless that anyone is planning something serious with her. So this answer came after i sent her a letter(parents won't let her bring her phone along,) in which among other things i told her how i feel , which resulted on her. answering with a letter too... The letter was the only way of speaking privately for the first time, since me and her alone would alert many things (Albanian culture). My letter(which was rich, a two-sided A4 with calligraphy) was delivered to her after i had left, secretly by a trusted person, on which it had my number and my e-mail. . So the weird thing was that she responded to it with a letter too, since she only told me she doesn't feel the same way. I mean why bother and just don't message me by phone with a classic "i don't see you the same way". Here is her response (her english is not my level) :

"I read the letter and i'm shocked. I really didn't expect this. I think that you have misunderstanded the things and our friendship. And i'm really sorry about that. I hadn't and i can't see you with another eyes, i only can see you like a friend and you should do the same. When a person likes another person he can't see the others around. You understand what i'm saying. Maybe i'm not in a relationship , but this doesn't mean that i haven't a guy im my heart, whose normally loves me too. So please, if we meet one day, we will meet like friends. OK! Is not the first time that guys, that i consider friend, look the friendship in another way. I don't want you, to be like them... OK! "

Knowing what i said on my letter (which is pretty big and non sense to quote it) , her response in fact SHOCKED ME. I simply told her how i felt from the first day i saw her, on which there wasn't any friendship formed yet, so there wasn't something to MISUNDERSTAND from my part. My letter was a short of a compliment to her appereance, and expressing my desire to keep in touch with her by our phones. Along with best wishes in her life till we meet again. And of course i respect our friendship. Now the part where she says she can't see me romantically nor did she ever saw me that way because she can't see the others around because of her "not in relationship maybe" situation is really confusing to me. I mean you love someone and he loves you too, what is that if not an established relationship? And does it mean that if she wasn't commited to that someone, she would see me from another perspective? Her English is so confusing... Plus the fact that she uses OK! with exclamation mark, what on earth does this mean? And finally, i think that she has the idea that it is HER fault that i simply fell in love with her, that she did something wrong during these days that made me look our friendship romantically. While in fact my letter is telling her that it's ME not HER! All in all, i would like if someone (preferably from Albania) could read between the lines of her letter, because i certainly can't. Is she rejecting me because of her "maybe not relationship but something " thing or is there more to it? She could have game me her number nevertheless as a friend, but she didn't even mention about it...
