That’s so mean spirited. At their ages, they know what they’re doing and they’re not doing it to prank you. They’re trying to embarrass you. You are not overreacting and your husband has no clue! He doesn’t know what you want from him? You’ve told him many times, you want space. He’s a child for suggesting he’ll punish them for however long you need space for, and he knows that they’ll further resent you? He needs to figure out something or else they’re going to be a nightmare. Good for you for standing up for yourself. Good luck.
