The idiom “harden someone’s heart” is commonly used to describe a situation where a person becomes emotionally cold or indifferent towards others.

One mistake is assuming that the idiom only applies to romantic relationships. While it can certainly be used in that context, “harden someone’s heart” can also refer to any situation where a person becomes closed off emotionally.

Another mistake is using the idiom too broadly. It should not be used to describe situations where a person simply disagrees with another or has a different opinion. Rather, it should be reserved for cases where emotional walls have been put up and communication has become difficult.
