My husband grew up in an environment where his family cursed at eachother and yelled.

I was not brought up in this environment.

Today my husband said “Fuck you” and “fuck off” almost loud enough for the kids to hear.

He also says things in front of the kids like “I’ll make it idiot proof” or “use your brain” in front of the kids.

Is this normal? What should I do? I’ve already told him I don’t like this language and especially him saying it in front of kids.
