DH and his excessive swearing in front of DC

[PennyPittstop]

DH and I have been together for 12 years. He's in the military so he's used to everyone at work not being shy about using swear words. I work in a male dominated environment where everyone swears like troopers too including me but when I'm at home in front of the DC I rein it in. OK, an occasional oh shit slips out but generally I make sure that I use more child friendly language around the DC. DH on the other hand is constantly F this F that F the other in front of the DC despite me asking him to zip it. 9 year old DS gets upset by it. 3 year old DD has started copying DM took her with her to the supermarket this morning and DD said the F word 3 times in one sentence even in the correct context. DM was obviously horrified and I'm mortified. How the hell can I stop DH from swearing all the time? I think he's at the point where it's so ingrained that he doesn't even know he is doing it. Every time I bring the subject up now he gets arsey with me and says that it can't possibly have come from him

Being military does not result in this!! My father was life-long military and never used profanity at home...my nephew is in the modern military and is extremely polite/respectful within his home environment too.
Record him. Record your daughter. Lay some boundaries. I can assure you he is fully capable of not swearing inappropriately at work and therefore is choosing to at home.

So ask him this: he's called in on a disciplinary at work. He's made a mistake and could get fired. Would he swear at his superiors then?

he drives me insane most of the time but we sort of rub along OK

If my daughter or a friend described their marriage like this to me, I would feel really sad for them.

he drives me insane most of the time but we sort of rub along OK (when I behave and not raise subjects he disagrees with).
