Are you or do you know someone is a victim of abuse? Any kind of abuse. I was one of those, that faced abuse while living with an ex-boyfriend. I escaped and survive with the help of friends and family.
Let me say that you do not need to deal with it. NO ONE deserves to be abused. Tell family or friends, they care about you and will help. If you don't think that they will help find a hotline to call or contact the police.
Here is some advice: Be prepared. What I mean about that is to have a small bag packed of clothes, money extra set of car keys, etc..and hide it somewhere where they won't look. When you have that extra moment and they aren't there, grab it, and leave.
Again, Talk to someone how can help and generate a plan for after you leave, where to go? What is the next step to be safe?
Some victims never make it out, others do. Don't let anyone control you, manipulate you, or treat you bad. I know it is hard, but you will survive and eventually be able to go on with your life.
