1. you don’t know who lied. the girl or the shadchan. if it looks good on paper, go out. if she lies when you ask her, her age, that’ll tell you what type of person she is.
2. her weight. so what? if you marry skinny and she gains weight after she gives birth, then what’ll you do?
i personally had a list of physical features i would absolutely not go out with. my wife was everything i said i would NEVER marry.
