DD 21 used to have anorexia, between the ages of 15-17. Obviously it was quite serious and she was very underweight. It was a scary time for us and her, however, eventually she had some health issues due to her very low weight and actually went to the doctor herself, unprompted and slowly started recovery. It was definitely hard for her, however a massive driving force for her recovery was focusing on her health.
At the time, DD was mortified by the damage she had done to herself and despite some initial issues, she was very cooperative with CAMHS, her recovery plan, etc... Even her doctors noted that she was very strong willed and determined to get better, which was nothing short of wonderful considering how ill she was and how anorexia can be such a gripping, long term mental illness. .
Some back story: When DD initially recovered, mental health services encouraged her to gain towards the higher end of BMI. This was mainly a safety measure in case she relapsed, and based on evidence that this can help with health restoration.
Aged 19, DD lost about a stone through purposeful dieting. Her logic was that she felt mentally ready and wanted to lose the weight to get to a (healthy) weight she felt more comfortable at. She was absolutely fine, however her father was very upset and felt she was relapsing. However, as I was the parent she was living with, I put my foot down and said she was fine. Which she was, there were no issues and she lost no more weight than the amount she had as her goal.
DD put the weight back on over lockdown. Two months ago, she started dieting down back to her goal weight. Again, she was very open about it. She’s now lost the weight, seems very happy and confident.
However, her father has since messaged me and said he has noticed her weight lost and is worried. He wants me to speak to her, or he will speak to her himself. DD no longer lives with me, but we’ve spent a fair amount of time together since lockdown ended and I have no concerns about her mental health. I also think she is an adult (albeit a young one) and at this point we cannot constantly act as if we are monitoring her weight.
I have absolutely no doubts that my DD is a young woman who has a healthy attitude to food and simply wanted to lose some weight. I have no concerns whatsoever. However, ex-DH is determined to say something to her. Last time this happened he created a massive fuss, started monitoring her food intake when she spent time with him, etc... to the point she felt uncomfortable being around him. They have a tumultuous relationship at times and I don’t think I am being unreasonable to not want this to occur again.
Am I being unreasonable or am I being sensible and treating my DD like an adult? How much concern should a parent have for a child who used to have an eating disorder, however has not relapsed in four years and is now a young adult?
