Cheating father, I told the woman he cheated on with my feelings

I found the woman on facebook who my father has been cheating with and sending my mothers money to. She said that I've given slandering and defacing evidence she needs for a divorce suit. If my mom wanted to get an alimony could the woman use my message to her which was no threatening besides a law suit, anyway of interfering with her case, a divorce has not been filed whatsoever. This woman and my father have destroyed our family. My mother has raised us for my entire life.
