I feel like a disgusting human being for saying this and all I want is for her to be happy, but is it bad if I want her to keep her body in shape and not to start letting go? I mean she was able to stay in AMAZING shape for sooo long and I don't want her to give up now

I'm sorry if I sound like an annoying exhale member who meltdowns over everything but that is not the case with me.
I mean she can do what she wants to do
