I can relate too. When I was about 23, and weighed a whopping 116 pounds (at 5'10", or 178cm), she told me my thighs were too fat for the jeans I was wearing (Levi's 501's).

I don't know why people feel the need to attack other's appearances. It's wrong and hurtful. Especially coming from the one person who's supposed to love you unconditionally.
