concerned about girlfriend with her husband

I was with a group of young married women the other day listening to them talk about their husbands (as women often do in groups) and one girl who is very new pregnant was telling an incident about her husband that concerned me very much. I just wasn't sure what to say other than saying to her 'You do know that is inappropriate behavior, right?'....apparently he had a temper tantrum because he couldn't find a particular piece of equipment to his uniform. So he proceeded to angrily tear the apartment apart. As in, throwing towels off the shelf onto the bathroom floor and leaving them, pulling clothes out of all the drawers and leaving them in piles all over the floor, that kind of thing. And leaving the girl to pick up after him. All because she told him she might have moved the piece and just couldn't remember. Being pregnant does that to a person's memory. So when she accused him of having a temper tantrum he was like, no I'm just looking for my belt. Um, no. That was being an a$$hole.

Anyway, my mental image was such that I just feel so much concern for her and the baby to come. I just have no idea how to say so, if I should say so, and how she might react to it.

To be honest, listening to their stories I just want to shake them and tell them 'don't take that, put your foot down'...lazy, controlling and bad tempers...what a mix. I guess it doesn't help that they are all military wives and I was one for 30 yrs, I see the path they are going down.
