I rarely have need of a term for such - but I suppose fondness, liking, have a bond with = that sort of thing. But for me, it rarely comes up that I need to articulate a term. I can't actually even come up with an imaginary situation outside of deathbed scene:

example

Scene - single iron bed, thin woolen blanket covering a dying woman who is surrounded by her closest friends. No sun, it is cloudy and drizzling outside (which is how I always want death scenes to be but no one I know has ever managed to shuffle off on anything but sunny, delightful days)

Friend 1: Oh dying friend, what fun we had
Friend 2: 40 years we have known each other - remember the hiking trip to X or the time we spent that summer exploring the boundary waters?
Stopdog: yeah we had fun

Dying woman: I am glad I had friends like you
Friends: us too.

The End

Even people I do love - we say it some but not all the time - in fact, for me, if a romantic partner keeps on about telling me about love all the time - I just get annoyed. Like I know - you already said that - let us move on to more interesting topics
