Hey glj! Perhaps your H is slowly realising that he is gonna have a son in the next few days, and he is seeing the picture of a happy family with both parents and a baby.. Yes, I think he is a wee bit jealous about your ex. Sometimes they think that you will be there waiting for him forever. Reality strikes them and they think "Hey, my wife is kinda attractive and other men are interested too", and then they get a little protective and defensive like "Hey...she is my property. I have her. You fellas don't" mentality.
Agree with you that there are a lot of similarities between the WAS attitude, and the things they say.
