I'm sorry you're going through this it sounds very strange, almost like he's afraid for some reason? I don't know why else he would check out like this. It's absolutely not unreasonable for you to be upset about it, in any case - especially when he was really very callous about your concerns last night.
Have you shared with him how his behavior is making you feel and the concerns it's stirring up? I wish I had advice to give but this just sounds so weird I can't really get a feel on it. Good luck, I'll be sending thoughts/good vibes your way ❤
If you are still having contractions I would call your OB ASAP. AS far as your Husband is concerned, it might be his way on coming to the realization that he is about to be a father for the 2nd time and the best way for him to deal is to not talk a bout it.
