The one about the partner pissed me off too. My SO and I will absolutely tell each other if we see the other eating too much. I mean, if we want to have a day where we overeat that's different, we compensate or tell the other one and it's never a frequent thing. But if I go the day with having sweets and pastries and fast food and shit you bet your ass my boyfriend is going to ask me why I'm stuffing my face. Chances are something is up and he actually gives a shit about my mental/physical health enough to ask, and vice versa.
