And has no regard for the health of our DS?
Just found out he's been feeding him raw food.
DS (14) has a weird thing where if it was up to him he would eat frozen food that has been defrosted, we have come down hard on him after one too many times catching him eating a frozen pizza defrosted 
(not envy)
Have explained about the bacteria dangers and now he only eats food that has been thoroughly cooked and then cooled down. We mainly cook from scratch here but also have the odd frozen meal, DS isn't particularly fussy, just prefers cold food over hot food and that's fine. Not fine to eat raw food though.
He also would smother all his food in salt if allowed but he knows he's only allowed a certain amount.
Ex and I have always had a good relationship and we've discussed DS weird food preferences before and he's always said he's always enforced the same rules when DS is round but just found out whilst talking to ex's DP that DS is allowed to eat frozen defrosted food and is allowed to cover his food with as much salt as he likes
AIBU to be pissed off with ex?
