He's not huge but he is overweight and it's all round his middle, which is the worst place for his health.
He doesn't see it as an issue and will continue to eat and drink as he chooses.
AIBU to think once you have dependants you should look after yourself a bit? Plus, you since he's gained the weight, he snores, which he never did when he was slim.
I get that it's not easy for some people to lose weight but he's not prepared to even clean up his diet a bit. Knowing how it affects those around him (me and DC) should he take responsibility and do something, or or is it his body to fill with junk as he sees fit?
