My ex-girlfriend suddenly texted me that today is April Fool's Day. Can you tell me that we have made up?

Since the ex-girlfriend said, "April Fool's Day is here, can you tell me that we have made up?" The implication is a fool's trick on April Fool's Day. You can also say "let's make up" to her. Because you are also her ex-boyfriend, she plays April Fool's Day games for you, and you play April Fool's Day games for her.

The crux of the matter is that if you want to express your true feelings on April Fool's Day, as the saying goes, "It's true when it's fake, and it's true when it's fake." That is to reserve a retreat for your feelings, rather than dare to love and hate. Love is a kind of right, a kind of freedom, a kind of healthy emotion (provided that it does not destroy her life), and love is open and honest.
