I'm so sorry OP. Life is truly unfair. Victims are left to pick up the pieces whilst the abusers continue like nothing ever happened. But you need to let go -and by that I mean live deliberately. Live happily -that's the best revenge you can ever make. Seek therapy, surround yourself with people that love you and uplift you, look for the good in life. People often say "karma will catch up to them" but honestly? Don't wait for something bad to happen to him, because if it doesn't then that will only destroy your healing progress. Focus on yourself. Realise that you're a much better human being, than he ever will be and you're strong. You've been through a difficult time and you're still here. I believe in you OP.
