DH was like this, this last pg and even for the first week after bubs was born. He only snapped out of it when I went completely mental and broke down at him about his lack of excitement. He was genuinely surprised, he didn't realise that that was how he was coming across. He was very worried about certain things, but he actually was very happy about bubs, he just wasn't showing it very well, because of he's fears and anxieties.
