Partner changes during pregnancy

Am I the only one who’s partner becomes a major hormonal moody dick head during pregnancy?! You would think he was carrying the baby !

The last time I was pregnant my husband was a HUGE asshole and we almost split up. But then he was good with our son and still is. Things improved and we were better.

But now I’m pregnant again and he’s being the same way he was first pregnancy and I honestly don’t get it Am I missing something? Is this common for men?
