allyn you seem to have married into a family, that shows you little support.
Right now, this must be making you feel very lonely.
Is your brother in-law, going to be living with you for long?...as it sounds like he's not happy with his life, to say something spiteful like that?...You two need your own space, but just make sure your husband, is kept fully aware of how you are feeling.
What an insensitive lot they are.
