One of my great-grandmothers was a WWI war bride from France. Her husband told her she couldn't teach the children French because he didn't speak it. The next family member to speak French was my younger sister who chose it from the list in high school when she had to take a language. Teach your kid your language. Please. If your husband continues to be a jerk about it, leave.

(I'm reminded of an AITA post where the husband was told he was the A and rethought his position and decided to learn his wife's language. I can only hope this guy will have similar growth.)
