Try not cussing around them. But tell them I'm making the effort, and I don't want to hear constant complaints from them about it. Complaints don't help, and just make me resent the effort to change.1

I swear like a sailor. I would be offended. your partner should love all of you, sounds nitpicky to me.
I would just sit down and discuss WHY it bothers him/her. Something small like that shouldn't be an issue with someone you are in a relationship with.
I've heard the "swearing doesn't make you sound very ladylike. It's my very classy" bs. They are just words. Very passionate ones, so fuck off ;)2
