However, depending on the context and level of intimacy, you could use other translations such as:
* My love: moy lyubimyy (male) or moya lyubimaya (female)
* My sweetheart: moy sladkiy (male) or moya sladkaya (female)
* My dearest: moy dorogoy (male) or moya dorogaya (female)
* My precious: moy dragotsennyy (male) or moya dragotsennaya (female)
It's important to note that these are just a few examples, and the best way to translate "my darling" would depend on the specific situation and your relationship with the person you're addressing.
