<human>: Friendships have always been a rare and big deal for me. So maybe it is just pathetic old me. But I made a very close friend in 5th grade and we remained friends throughout high school. I doubt if I was ever her best friend as much as she was mine (she was more outgoing), but we understood each other deeply and confided in each other.  

After graduation, she went into the military across the country. We emailed each other about 5 times over a year and a half, but then she stopped.  Since she was the closest person to me I felt devastated. But I wasn't going to go begging for love that someone didn't want to give on their own accord.

A long time later, maybe 2 and a half years, I decided to "try"her again, and sent her a friend request on Fb. She accepted, but didn't say anything to me.  So I was, and still am, left hanging and feeling betrayed yet again. (she still lives across the country)

Sometimes I wonder if I even should feel betrayed. Is it that our friendship doesn't seem like such a big deal to her anymore--i.e., does she just not understand? I know that the military can be a life-changing experience and that you can easily adopt a huge circle of very close friends (although she was never in combat), but does that mean you can be excused for leaving a childhood friend in the cold? As if nothing ever happened?

Is it something I did? I used to have some overly-strict religious beliefs (indoctrinated from an early age) which caused me to criticize her sometimes (very gently) out of a (misguided) concern for her. I know that my last email to her had something like that in it.  It was a terrible thing for me to go through myself--and I don't blame myself for it, but perhaps it also offended her enough (though she never revealed any offense before) to never speak to me again.

Should I feel betrayed?

Can you provide a brief overview of the text?
<bot>: Close friend from childhood went in military, stopped talking to me, accepted friend request years later, but never talks to me. Why?
