I'm uncomfortable with the idea that
feminist thinkers should be an authority on male friendships, since by definition feminist thinkers think from the point of women, and here we are discussing friendships between men.
I've a couple of female "friends"[1], and generally when talking to them I often feel all they're doing is telling me how right I am to feel in such and such way, frequently highlighting the differences between "us" and "them", whoever "them" might be, whenever the opportunity arise. (I suppose you'd call that 'gossip'). I also find often their opinions aren't decided till they figure out everyone else's, as if a fact cannot be correct until it is agreed on by other people. And when I speak confidently about a non-conformist view, they're often reluctant to outright disagree with me until they're sure my view is non-conformist, which might be weeks later when they suddenly bring it up (I assume after having quizzed all their friends).
I've been called a "best friend" half a dozen times by other men in the past year or two, but I've only got one best friend myself, who I've known for close to a decade, and we talk most days of the week. I think one of the most important qualities in a close male friendship is to mean what I say and say what I mean, even if no one would agree with me, even if it offends and hurts feelings. I think that is the stuff male bond is made of. It's hard to feel closeness when a friend is hiding what they really think about me from me[2]. To maintain the closeness of a male friendship, it's also important I put it above any romantic relationships I develop with women, even, and especially when, the women in such relationship puts pressure on me to become closer to her than to my friends. If I was "Matt" in the article, and if the author was my best friend, and a very important one at that, I would rather divorce my wife than move, if the move would endanger the friendship I had with the author. Only this willingness to sacrifice would ensure the strength of the bond in the friendship[3].
[1] I don't consider any female as "friends" even if they think I'm theirs, because of [2].
[3] It is also my opinion that "following" my wife wherever she goes and agreeing with her every word would reduce her attraction for me somewhat. http://www.telegraph.co.uk/science/science-news/10524035/Hap...
