Just weeks after opening up about the devastating diagnosis facing their newborn twins, reports have emerged that Jesy Nelson and her fiancé Zion Foster have gone their separate ways — despite announcing their engagement only four months ago.
The former Little Mix star, 34, and Zion, 27, welcomed daughters Ocean Jade and Story Monroe Nelson-Foster prematurely last May after a traumatic pregnancy and an emergency procedure. But the challenges did not end there. The twins were later diagnosed with spinal muscular atrophy (SMA) Type 1 — a rare and severe condition that causes progressive muscle weakness and life-long disability.
Earlier this month, Jesy bravely told her followers that doctors at Great Ormond Street Hospital explained the girls would likely never walk or regain full neck strength. She said they would be disabled, adding that the only option was urgent treatment and hope. Jesy admitted that without it, her daughters would not survive.
As the couple tried to process the shattering reality, Jesy also spoke openly about grieving the life she once imagined. Now, sources claim that emotional strain proved too much for the relationship. According to an insider, Jesy and Zion remain friends, are united in co-parenting, and are fully focused on their daughters’ wellbeing.
Experts say it is not uncommon for couples to fracture under extreme trauma. Chartered clinical psychologist Tracy King explained that overwhelming stress can push the brain into survival mode, causing emotional withdrawal, reactivity and breakdowns in communication — even where love remains. She added that intimacy often fades, not due to rejection, but because the nervous system prioritises protection over connection.
Psychotherapist Susie Masterson noted that shock can trigger learned coping responses from childhood, including searching for “escape hatches” such as emotional withdrawal or walking away from a relationship in an attempt to regain control. Meanwhile, relationship specialist Ioana Rotaru warned that early warning signs are often subtle — emotional disconnection, resentment, irritability over small issues and one partner forcing themselves to be “the strong one”.
Performance coach Wendy Dignan described such diagnoses as a “pressure cooker”, saying couples often cope in very different ways — one becoming practical and solution-focused, the other emotionally overwhelmed. Without space to talk, that difference can quietly drive distance between partners.
While experts stress that adversity can sometimes strengthen bonds, they agree compassion is key. Consultant psychologist Dr Joanna Silver urged parents to remember there is no “right” way to respond, encouraging small moments of connection and kindness to oneself during an impossibly complex time.
