Was there violent behavior on the part of the husband in your friend's case? Because, frankly, I think a violent husband changes things a bit. IME (and not just my own but from years of working in and training for crisis hot lines), most wives think they know their husbands best and how to tiptoe around them to minimize risk. It's a tightrope. Even if the man has never been violent toward the wife in the past, the divorce period ups the rate of violence.
Where a man is known to have been violent with others, the risk is higher for the wife. BLM was charged in Indiana with assault, not too long before he left Indiana. He managed to plead out to a lesser charge but the person he attacked (who was running for mayor of Indianapolis) has told his story on an approved source for WS (Gray Hughes).
Was your friend's husband similarly violent? Because to me, a man who loses it in public, while at work, is a man who is not in control of himself. He probably needed anger management, but apparently instead the couple left Indiana and moved to Colorado, where he has apparently not filed paperwork to start a landscaping business, and works as a volunteer. Would he pass an actual employment process to be a firefighter, with that disorderly conduct conviction? I wonder.
Anyway, not all divorces are alike, and there are red flags in this one.
And we're not talking "losing it" in a merely verbal way. There was a verbal disagreement and BLM lost it and physically attacked someone - because he was mad that other contractors (plumbing and electrical IIRC) were still working/still had trucks in place when he arrived to do landscaping. That's just not reasonable, from my perspective. Not all divorces involve an unreasonable, violent man. That may be what we're looking at here.
