I've heard this said SOOOO many times (mostly from the older generation) when they talk about a guys bad habits... as if a life time of a bad habit can magically be changed by his wife/partner..
Like with DH, his family has mostly eaten fried, fatty food..so he's over weight. I'm a very healthy eater. so mil CONSTANTLY goes on and on ''you have to change his habit, get him to eat healthy'' ...umm your the one who got him into the bad habit in the first place, for past 30yrs of his life, how to you expect me to change it ??!! (oh and i have been trying for 6yrs!! )
Another...my bf's DH is a smoker, started at a young age, parents didnt bother stopping, but they constant nag my bf to help him stop ... and yes she has tried but bad habits are hard to change
