Right off the bat when the SIL said some people don't belong around nice things OP should have asked her what a brat like her was still doing there. Or throw wine at the husband's family and see if they still think it's funny.
Madison cost daniel his marriage to Claire after Madison embarrassed Claire's parents in front of every single person inside of the restaurant they went to.
I know rich people who are gracious, kind and down to earth. This family prove that money isn't the same as class. Also if OP had $$ from granny, it should have been left to the parents.v
From the very first comment those in laws should never have been invited back to your table. I don't know why you kept putting your parents where they were insulted and looked down on. Your husband is a jerk. One time and nothing done would have been enough for me. Divorce the weakling and move on to a better life. Protect your parents.
Why should the husband say something, why couldn't OP say something to her in laws? Yes you tend to manage your own family but that doesn't mean you allow disrespect to grow until it's insurmountable.
see this is why people call me abrasive and confrontational because im sarcastic and have zero filter scene or not i call out the bullshit when someone is cruel why is defending yourself and those you love not acceptable bit causing a scene in my opinion its cowardice dressed up as keeping the peace
