A woman whose marriage ended eight years ago due to her ex-husband’s affair has maintained an amicable relationship with him for the sake of their two children, now 18 and 20. After the divorce, she focused on moving forward, setting aside her personal feelings.
Recently, the woman was diagnosed with epilepsy and began medication. When her 18-year-old child, who currently lives with her while deciding on post-high school plans, casually mentioned the diagnosis to his father, the ex-husband called the original poster (OP) and yelled, demanding to know why he wasn’t told immediately, arguing he had a right to the information as the father. The OP, feeling that their children are adults and that she will likely manage her condition well, is now questioning if she was wrong for not informing him sooner.
AITAH for not telling my ex about a life changing illness
As renowned family therapist Dr. Terry Hargrave states, “When co-parenting after divorce, the focus must shift from the partnership to the parenting. Information sharing should align with the needs of the child, not the needs of the former spouse.”
The dynamic here involves a history of betrayal and an established post-divorce boundary where the OP seems to have successfully separated her personal life from her co-parenting duties, particularly since the children are nearly independent adults. The ex-husband’s reaction—yelling and asserting a ‘right to know’ about her personal health—suggests an attempt to re-establish control or involvement in her life that extends beyond necessary co-parenting concerns. While parental concern for a child’s home stability is understandable (especially with the 18-year-old living there), the OP’s diagnosis primarily affects her own health and ability to drive, which are personal matters once children reach adulthood.
The OP’s action of not immediately disclosing the diagnosis was appropriate in establishing and maintaining necessary personal boundaries in a post-divorce environment where the relationship is purely functional regarding the children. In future situations, constructive communication would involve informing the ex-husband only when the diagnosis directly impacts the established co-parenting schedule or the child’s immediate care needs, rather than preemptively sharing all personal medical updates.
THIS STORY SHOOK THE INTERNET – AND REDDITORS DIDN’T HOLD BACK.
The original poster is facing a conflict between maintaining personal autonomy regarding her private medical information and addressing the ex-husband’s strong feeling of entitlement to know about significant life events affecting the children’s environment. She has prioritized her emotional stability and the children’s well-being by keeping things civil, but this boundary around personal health information has now been challenged.
The core question is whether the OP breached an unstated responsibility to her co-parent by withholding a new medical diagnosis, or if her decision to disclose information only when she felt ready, given the children are adults, was a justified assertion of her personal boundaries. Should adult children’s parents always share significant medical news immediately, regardless of the relationship status?
