While there are no simple fixes, there are several things parents can do to help their kids deal with abusive relationships. These ideas might help.
Take the time to talk with your teenager about abuse — what it is and how to deal with it. Let them know that they are far too valuable to accept abuse. It is never acceptable for anyone to manhandle or verbally abuse them. Then take the time to help them identify abusive behaviors and patterns to be avoided.
Abusers often try to isolate and control their partners. This is one of the first warning signs that your son or daughter may be in an abusive relationship. If you suspect abuse, lovingly encourage your child to surround themselves with friends and family members — this is a time to press into relationships, not recoil from them. Encourage them to get active in church, volunteer with organizations, and expand their interests.
Don’t accept the excuses your son or daughter makes for their partner’s abusive behavior. There is no excuse for abuse of any kind. Yelling, pushing, possessiveness, insults, and intimidation are signs of control. Remind your child that they have the power to end this relationship now. Everyone deserves to be respected because everyone is precious in the eyes of God.

 Psalm 139:17–18
Don’t stand by and watch your friend suffer abuse. Yes, this is classified as abuse, and we need to recognize it as such. Anything a person says in an attempt to belittle and control another person is abusive. Your first job is to help your friend understand that love is not supposed to behave this way, and they should not consider dating anyone who hurts them or thinks so little of them.
The Bible says, “Do not be deceived: Bad company ruins good morals.” An abusive and belittling partner is bad company. Not only is an abusive partner bad company, they are poisonous to your friend’s self-esteem.
If the first step is seeing this type of abuse for what it is, the second step will likely be helping your friend see and embrace that they deserve better than the treatment they are getting.
More than likely your friend will tell you that their partner is not like this all the time. And they probably aren’t. But abusers almost always try to isolate and manipulate their victims. You friend may be fooled by her boyfriend’s charm and attention, but if he has already demonstrated an abusive pattern of behavior, it will only get worse if she continues to allow it.
Helping in these kinds of situations is never easy, but as a good friend you can and should gently and lovingly let her know that she is not alone and that she does not have to take this kind of treatment. She is worth more than that to you and to God.
