Coming from someone who doesn't like to hear details you might want to ask him what makes him uncomfortable about it. For me it's that I make myself crazy comparing every little thing. She is different from me, they have a different relationship. Not everything has to be exactly the same. I know that in my head and I'm working on feeling it in my heart too. I happen to be a very competitive person and I'm trying to reframe relationships in my head into something other than something you "win".
