Needing help with Revenge Flooding

Recently I've discovered where my wife's affair partner not only works but also lives. I was floored to find out, with his NEWLYWED WIFE, whom I happen to know. I want so badly to ruin this person's life as they have destroyed every aspect of who I believed I was. My confidence in my self & everything I've become in life, teeters on the brink of destruction due to I thought I had made it thru the storm only to have everything brought back to the forefront. My spouse & I recently moved because I was offered a dream job that could absolutely be a life changer for my family but now thru this discovery and the avoidance of my spouse never answering any of my questions, I have placed my family, mere miles away from her AP. Being a prior Marine & a Gulf War Veteran you can probably imagine what has engulfed my mind, not to mention I want to spare the AP's spouse of EVER having to endure what I have endured mentally & physically over these excruciating 3 years. If it wasn't for my absolutely gifted 9yr old son & beautiful 8yr old daughter I would use all of my talents to just disappear & never be heard from again. On the other hand I seek Vengeance almost hourly in my mind & I feel it will consume me eventually if I can't find away to cope with all of this deception. I want peace to be back in my mind & my life, I want to lie down in green pastures & actually hear the still waters, what will restore my soul?
