all of these are true, as ive been in the same situation with different people, different friends choose to open up differently. Different times, different place, etc. It all depends on the type of person he or she is. So i wouldnt worry about it personally, if u feel like you can trust her then do so. Dont push. Just let things flow. I know how you feel with the frustration and confusion but there really isnt any you can do. (You cant force the girl lol) I think you get my drift and what im trying to say .. right? i hope so. I hope this helped. When she feels ready, she will open up. Dont worry!
