I expect it's part of a pattern of 'uncaring' behaviour. Or possibly something even worse, given that it seems he's actually had to go out of his way to damage your clothes (picking them out of a separate laundry basket, despite having been told to leave them alone.)
So OP, do you think it was intentional?
What's he like about your clothes, generally? Have you eg stopped wearing some things because he thinks they show off your body too much? Does he complain if you wear make up, or police your social life?
Is he controlling and abusive like this OP?
Yes, I may be way, way off track here, but underwear, especially pricy, delicate, needs-looking-after underwear does have certain associations with sex, and the fact that his destroying it has an element of calculation suggests that he maybe has some issues about sex or, more to the point, your sexuality
Does he have issues about sex?
Or is this a complete overreaction and he just wasn't paying attention?
And it annoys me that if someone was to come on here and post about their wife shrinking their satin boxers, they would be told to get a grip and wash their own undies, however in this situation, the DH is accused of being controlling and abusive.
Sometimes we all make mistakes, doesn't make it abuse.
