I agree with her. I had a bunch of mates from school - we were a big group. Eventually, we came to realise that we were only hanging out together because we had that "we've known each other for 16 years" tag. We decided to call it quits because we didn't actually derive that pleasure from each other. We all felt like the others were taking advantage of us - it wasn't that we were, but we all had grown up and moved on.
Our friendships are largely meeting people at times in our lives and we all help each other out in whatever manner we need at that time. There is nothing wrong with that.
I am not sure she goes about expressing herself in the correct manner though.
