Like what I had said in other posts - you can't expect things to
return back to normal once you had leap across the chasm towards
another phrase of your relationship/friendship with her. Just like
when you grow up, you gradually grow out of playing with toys and
it's ridiculous to expect you to do the things you used to do last
time (or even LAN gaming for 13 hours in a day for example)
The issue here is that you AIN'T the problem and the key to what
you want this friendship to turn out - its all about her. If she
refuse to acknowledge that fact in her mind, even if you give her
10 years, she will still avoid. You can't expect her to confide
everything, giggled when you both met, now because you have enter
into another phrase of your friendship and now, the ball is in her
court.
Do what you can. If
you can't return back to normal - the least you could do is to
prevent this friendship from slipping further.
Cheers
