Real friends

As I sit and watch this movie about the closeness of friends, i wonder why it is that reality is such a disappointment. Why can't there be real friendships like that? Granted, i have friends, only a select few are trusted enough to be in my inner sanctum, and only one is close enough that i call her "sister". She knows me as no one other does, but still....we are not like those girls in the movies. I have to admit that i want to have a friendship like the girls from Sex and the City. Girls trips and always being able to count on one another for anything. 
How is it that i used to have so many people i could call friends when i was young, but now i have only 2? is it that as a young person my standards were lower? or is it that i was more open to friendship? I spent many years being friends with people who did nothing but stab me in the back and treat me as if i didn't matter but i was ok with that because i was never bored on a Friday night. What does that say about me as a person? Does that make me the needy wretch who is willing to get trampled just to be able to say she has friends? Or was that normal behavior for myself and my peers?
I love my friends, the ones i have now, and i hope that they love me back, but i sometimes wonder if its normal....i unlike the ladies in the Bushnell books, can go days, sometimes months without talking to my gfs and not think anything of it. Does that mean that I am cold or that i dont care about the relationships as much as they do? I tend to be the same with everyone, even my parents. Outta sight outta mind. I think that might come with being married to the military. I have learned to not let distance get to me in any way. I am not effected emotionally by the same things that most people are. I often wonder if that little fact makes me a socio-path, at least in some small element. I wonder from time to time if i am normal at all....if im goin to mess up my kids by teaching them to "be strong" like i am. Not to cry when they feel sad or feel the need to just simply shed tears.
What sort of example am i setting if I can even cry in front of the people that i am supposed to be closest to?
