I hadn't seen his body for months because we hadn't been sleeping together. Dan pulled off his T-shirt - his sculpted chest and torso had been replaced by jutting ribs and a concave stomach. Dan was anorexic. And it was my fault. We told his mum - she took him to their GP, who referred him to a therapist.
I kept encouraging her to eat though and she slowly made progress. But our relationship suffered as we argued under the pressure. I often went to the gym to let off steam - getting in shape was a bonus. I started reading magazines about men's health and was spurred on by seeing athletic guys on every page. I wanted a six-pack too, so I ate a strict diet of just 1,000 calories a day and worked out to burn off 600.
Mary George of B-eat, the UK's leading eating disorders charity, says: "Eating disorders are almost always linked to some sort of emotional trauma, so I'm not surprised to hear that caring for a partner with bulimia has triggered an eating disorder. If the carer has body issues buried deep somewhere, then dealing with the day-to-day illness could bring them to the surface.
