I have to say I just don't understand it. I've been reading all sorts of threads, about spouses who've gone bats in one way or another--but I don't understand how your W could supposedly not want you, ignore you for so long, and yet be so genuinely upset about your friend.
I don't know what the end result will be, but your seeking companionship elsewhere certainly hasn't done any harm so far, unless it has harmed your friend.
