As great as that would be, I realize I have left out some information. My brother is not unstable at all. He loves his daughter. He refuses to leave his wife since she has been diagnosed. He says he wouldn't leave her if she had cancer and he won't leave her because of this. They fight all day long. About a month ago they were both arrested for domestic battery (against each other). All charges have been dropped. While in jail her parents had the baby. They continued to have the baby for 2+ weeks after that because the parents' house was unfit for the baby to be in.
On top of all this, they both have other kids. She signed over guardianship of her other daughter to her parents as she couldn't care for her and didn't want to care for her. My brother has 3 kids with his ex. His ex went to prison for drug manufacture and both my brother and his ex sign custody and guardianship over to his ex's mom.
