Thank ya'll kindly for responses so far.. It's a lot of information to take in and think about.. I know it's hard to reply to something briefly summarized like the OP, yet actually very specific and detailed.
I don't always need someone to talk to.. I don't always want people to talk to either. I just wish, the times I did want to engage with my best friend, she was available. If being in person wasn't necessary for people to bond, I have a feeling that not only would long distance relationships work out more, but there'd be a whole lot more of them. It's not that I ever doubt that she's my friend.. I just doubt how close she is anymore. If the probability of being rejected with no answer is so much higher than being answered, I'm probably just not going to contact that person anymore. This is a harder decision to make when it's my best friend, however.
