Dear Carolyn: My ex-husband is obsessed with our 7-year-old daughter’s hair. I once had it cut a few inches below her shoulders, and he threatened legal action. He said it caused him harm — that he couldn’t look at her for days. I’ve asked him to maintain getting her hair trimmed since he is so concerned about her length. She just had it cut, and it looks nice and healthy. My daughter likes her long hair, and I’m okay with it as long as it’s taken care of.
