AIBU my mil is so thin, I think she has an eating disorder. I don't say this lightly as someone who gre up with my best childhood friend being severely anorexic and having to be hospitalized several times I get really triggered by my husband's family attitude towards food. Tbh it never really bothered me until recently when I gave birth to DD and started thinking about how this would affect her growing up. I'm also just fed up as every time I see them it seems to crop up in a conversation. DH dads is a retired GP and clearly has strong opinions about overweight people. I don't care how people live their lives but it really grates me every time we see them they go on and on about portion sizes at meals, they even did it at Christmas last year and gave everyone tiny portions and said it was good for us. MIL talks about her weight, other people's weight and obesity and portion sizes and calories every time I see them. Honestly irritates me so much I can't take it anymore. Makes me want to gorge just to annoys her.
