Using curse words in front of toddler

As

So, I’ve heard people say it’s not that big of a deal. However, I am wildly against the use of curse words in front of my toddler. I think they are a lousy excuse for poor language and use of words not to mention it’s tacky. Her father has a sailors mouth and curses constantly, says he’s working on it. He will literally say “ get out of the fu***** bathroom” like what? I couldn’t tell him enough to stop that. It’s enough to make me strongly start disliking him
