<human>: My best friend is very confusing. She claims to think of me as that and always comes to me for her problems, but she only sometimes helps me with mine. Recently one came up and she asked me to explain so I take some time to write it all out and it came out pretty long and informative.

This was three hours ago. Naturally, I called her because I wanted to hear her advice on the topic but she didn't answer. To add on to this, I know she's not busy because I saw she had updated her Facebook via mobile so she has had tons of time to get back to me and that's what pisses me off.

You're probably thinking, "Calm your nuts kid, you're overeacting over one little thing," but no. This has happened countless times. Whether it be just a normal conversation, us venting about things, or anything else, it's become a reoccuring thing now where she just doesn't feel the need to get back to me. I would say about 40% we actually have a full conversation until one of us have to leave so we get a proper goodbye, but more often than not it's just *boom*, nothing back from her.

I should probably just ditch the bitch but the only thing keeping me from doing so is that 40%. On the rare occasions she does get back to me she's extremely helpful and caring. In person she's great but that's not gonna matter anymore since I'm moving a couple of hours away so the friendship is pretty much gonna be all through text, Skype, phone calls, etc. I guess what I'm trying to say is that my best friend doesn't act like my best friend and I don't know quite what to do about it.

Can you condense the text into a few key points?
<bot>: Best friend" doesn't give me time of day 60% of the time, but when she does it really feels like a good friendship. Fed up with how she rarely answers texts/calls. Need advice on what to do.
