When I was younger I remember feeling real sadness at letting go of a best friend I'd had all the way through primary school... To be honest she was becoming a very very different person to me, but it was a hard tie to break.
Now, since uni, people getting into relationships, and moving around the country etc - a lot of those I would have considered best friends - I rarely talk to. But, I know that whenever we see each other, nothing has changed. And I know we'd be there for each other, but must also accept that they may no longer be able to drop everything.
I have lots of good mates (mates verging on friends if you like) locally, but wouldn't put upon them unless I really had to - I think many of them would be happy to be there for me in dire straits but I don't wish to push that, hopefully I won't ever have to. My flatmate is one who I could truly rely on, however, as scatty as she is

And the boyfriend automatically sits in best-friend status as he's already seen me bare my soul.
I do have one friend who I was close to while we lived together - mainly because she's so intense that you can't be her fairweather friend. Since living apart she's almost tried to keep a hold on me, and I've felt obligated to go on nights out I knew I wouldn't enjoy, because she'd throw a hissyfit if I didn't. Thankfully now she's realised that I don't enjoy myself and has stopped asking...
