Now come to find out he went on AshleyMadison website and "claims" that he didnt look at it and he only saw a youtube commercial.....There were several entries for the website alone and even other girls names in jacksonville and st augustine where he went to school at.

He never "perfect and I was just digging because I wanted to ruin his Fathers Day Weekend! The NERVE! He is so insanely SELFISH THAT I HAVE NO CLUE WHAT I EVER SAW IN THIS GUY! He's only done stuff to hurt me.
