Dear Eric: A few years ago, my 24-year-old child came out as nonbinary and chose a new name, “Avery.” While the adjustment hasn’t always been easy, most of our immediate family now use Avery’s new name and pronouns. The exception is my husband’s parents, especially my father-in-law, who does not accept Avery’s identity and has criticized them about it in phone calls and texts. As a result, they are now estranged.
