I'm not too bothered about labels like 'friendship' myself personally, I've learnt in the last year or so to place no importance in what they are in words. In my heart I know what my relationship with someone is, perhaps there's a word to describe it, perhaps there isn't.

Thus it doesn't matter to me what a 'real friendship' is, because my relationships with people are each different and it would be pointless assigning a word to describe each one. :D
