Agree. My daughter, who has been married for 4 years now, constantly refers to her “ex” even though she is in her first marriage. In her mind, the boyfriend that she lived with for 3 years is her ex. My advice to her has been constant. 1) he is not your ex because not only did you never marry him, you were never engaged and 2) after all these years why do you still even talk about him.
How does he actual husband feel about his predecessor being bandied about constantly?
