You could also experience guilt, as you couldn't prevent the abuse to happen. You might feel guilty because you didn't know what was going on or didn't recognize the warning signs. Some times it is guilt what makes you feel like you owe the survivor something because you couldn't protect him/her on time. 
​After a friend or family member learned that a person they know has been abused in any way, blame can be felt in different ways—towards the person who perpetrated, towards others who didn’t take action, the justice system and even toward the person who experienced the abuse. 

What can you do?
Remember that it is always important to talk about your feelings with a professional, so you can learn to manage them.
