How do I deal with a disrespectful brother?

There is a Bible verse that in essence says, "you reap what you sow." Some years back I had a friend who said to me, "If that's how they expect me to be, that's how I'll be." That was not a good thing, for people expected him to be bad. I told him he didn't have to let people dictate how he should be. He had the freedom to do the right thing. He realized he was letting other people control him instead of him controlling himself. When my brother was a teenager, he had a period of time of bad behavior. Our father had a heart to heart talk with him and let him know how much he was loved and how hurtful his behavior was to the family. Realizing how much his family loved him, my brother changed his behavior. If you care anything about your brother, let him know. Also, encourage him to do the right thing for his daughter. I don't think you can ever go wrong showing love toward another person.

I can't tell you what actions to take but my advice is realize it's not your responsibility! This will make you feel a lot better hopefully it doesn;t mean not to help but it wll take some pressure off try to put out good energy and forgive!

for the sake of your niece got into the custody battle and make sure you get full custody... let your brother know you love him and would do anything for him but he is unstable right now and is unable to care for his child so you will be taking over get away from him if he is abusive. I know you love him but you don't have to take be harmed...
