Rum, I understand your feelings but I guess you are missing something. You have been talking with her over the phone for sometime but not yet sure about her feelings. Dude, when you love someone as much as you do then you should go ahead and tell her everything that you feel about her. If she understands your feelings and ready to start relationship with you then what could be better than that. If not, then she probably likes you and wants to keep a good rapport with you but not ready for any serious relationships. So my suggestion is just go ahead and express everything you feel about her. Another possibility is that she likes you and is also thinking about you as her prospective partner for future but for some reasons she is not sure whether you are all what she wants. Remember you have been loving her since childhood but she might just have started fresh with you in which case, I suggest you to give her some time to think about it. In either case, be expressive and communicate with her and let her decide about it. If your love is true, you will get her.
