I know this is very very hard. I'm so sorry. But....
Anger at something that is over and done is not going to fix it. Maybe your lawyer will send a letter to your husband's lawyer "apologizing" (in lawyer speak, of course) for being a dolt. Maybe he won't.
Your lawyer sounds like he believes in principles. That is a good thing. At the risk of sounding PollyAnnaish, maybe this is a positive after all.
Your husband was just called on the carpet over his shenanigans. Is it what you wanted? No, but as an officer of the court, your lawyer may have felt an obligation. (I don't know this, obviously)
Please, so you don't go batty, try to see the bright side here. Your husband was dumb, got called on it, now he has to fix it.
