Aunt's advice is great, but I'm not sure about the facebook thing (What did your brother say, by the way?) My inlaws are on my facebook and I really really wish I hadn't done that, as they occasionally use stuff on there against me.
(For example, they refused to call us back when we found out the gender of our baby when I was pregnant, because they wanted us to tell them in person. They live in another province. Then when one of my friends accidentally mentioned on facebook that we were having a girl, they got mad at me.)
