My DH is pretty much the same and I did once ask for advice on here.
I got the same rash of stupid answers telling me to leave him. Please STOP, its not about OP's relationship - the question is about dealing with her husband's rudeness. If she wants marriage advice I'm sure she'll ask.
That's not what she wants to hear and its a silly thing to say to a couple who have had a relationship long enough to produce a daughter of 'boyfriend age'.
My daughter brought a delightful boy home who was very overweight. They did eventually marry and have a son and are happy. She arranged for him to come to meet me first and together we explained about DH's 'problem' to new boyfriend so that when we did have the 'formal' meet the family tea he was ready for the impolite remarks about his weight. DD was ready for him too and told him in no uncertain terms that weight was off the agenda. DH hardly said a word through the visit.
He won't change, and will get worse - we've been married 63 years, and i do a lot of eye rolling and face-pulling when we're with friends - and they all know what he's like and I've stopped being embarrassed.
Well clearly the OP isn't as exercised by the replies she's had as you are, because she's expressed her gratitude at the response!
If you present a relationship problem within a marriage here on GN and ask for advice then it's inevitable that some of that advice will be to question whether you want to continue with such a marriage. Especially if your partner is gaslighting you, blaming you for his own failures, and refusing to discuss or change his behaviour.
You've found a way of dealing with similar behaviour, but that doesn't mean that everyone can or will want to do the same as you.
I'm sure the OP will reflect on the replies she's had and make up her own mind - as people generally do. However, she appears to have appreciated the different responses, so I don't think you can say that "it's not what she wants to hear". I would assume she simply wanted to hear what others thought.
