As tempting as it seems, do not bad mouth your abuser to others. State the truth as things happened when necessary, but bad mouthing just for the sake of it is not going to help you.
Read Job 27:4 and Psalm 71:24
We should constantly be thinking on Godly things and matters. When you speak about negativity and strife, then you invite it into your life. However the same is true when you speak of Godly things and matters.
Read Philippians 4:7-9
When you think on these things then you will begin to accept them into your heart and be able to begin to thrive in your life. When you bad mouth your abuser it is just another way that you will continue to give them power and control over your life.
So meditate on the things of God and you can have the peace that passes all understanding.
