My husband made fun of me in front of my friends, which made me very unhappy in exchange for everyone's laughter. Especially in front of female friends, I feel very embarrassed.

You are right, and you are not petty. In front of friends, they all want their husbands to be kind to them, which will make them more comfortable and superior. Maybe your husband didn't mean to make fun of you, but he didn't know what to say in front of your friends, so he could only take you as an example. You can tell him clearly that you don't like this way and there is no need to get along with friends.
