Hey Mainhoona, I have also same kind of problem. Actually I was thinking to share this with other guys in Sajha but I couldn't gather that much courgae. Now I am inspired with you. Now she is 21 and I am 29. I know her from her childhood when she was in class 5. Now she is 21, Oh my god how fast the time passed ! She also calls me "dai" but actually we don't have any kind of family relation ! We use to talk in the fone for more than one time in day and talk hours. She shares everything with me and I also do the same. I don't know whether I am in luv with her or not. But My heart is not that much strong to say " I luv u" to her. I have no idea about what she thinks about our relationship. I don't know how long it will go with so confusion..........................oh god !
