It's always tough to live with a family member. You most likely did it when you were young and then moved out for a reason. It's so much easier to maintain a healthy relationship when you don't also have to share a bathroom or a kitchen with them.

You get to witness close-ups of their little habits, quirks, and shortcomings, and they can grind your gears no matter how respectful they are.

A bad roommate completely ruin your life if you let it. Doubly so if it's your family. That's why one woman's husband was so upset when she allowed her younger brother to move in with them while he saved up money. Read on for the details.
