Ok, my brother and his DP are obese, and as far as I know, they're doing nothing to counter it. I think they have a fairly unhealthy diet, do no exercise, etc, and have steadily got larger over the past few years.
I know that one hand, it's their life, and their choice, but on the other hand, I only see their health deteriorating, and I think as a couple, they reinforce each other's behaviour.
I know when my mum tried to mention it a while ago, he reacted quite angrily, saying he didn't care.
AIBU to care? What can I do?
