Friendship - Persistence!

This post is after a recent visit to my native over the long weekend.
Attended a friend's wedding, she was my school senior still we shared a very beautiful friendship. she had given all the help, care, affection, advice which i always needed. we've spent lot of time together, going out, talking over nights, exchanging secrets, what not!
i was kinda stunned during the wedding.. partially out of happiness and rest cuz of the way our friendship is gonna be after this!
i do not really imagine a great bond physically after this, meaning exchange of phone calls, meeting up whenever we find a small chance also and a list like this. in fact once she got engaged only, i could find a major difference in our friendship. I'm still not convinced with the fact that this happens only with girls or it depends on the individual. i really see greater number of males who continue friendship over life, but real less number of girls.
so what about me!? i want to speak to my friends well like how it was when we were together. but i don't find the same enthu or response from the other side due to which i lose interest too.
this girl has been telling me from the time she got engaged that this will go for only few days, that I'm not finding time for other things, but later things will get normal and everything will be back in place. I still feel chances are very less. Is it that girls turn too responsible after the wedding, too busy taking care of family that we forget to take care of ourselves?
For the moment, I wouldn't call this greater range of contact as being together always, but juz having regular phone calls, the time which we take out to call each other, sharing things, laughs, happiness thereby letting each other know that the friendship we shared once is always alive n that We'll be there for each other always!
