Suspect the Worst
Go to the gym, no headphones! That’s cool, house is five minutes away. Pull up in front of my house and see work buddie’s car out front. Walk in house through open garage. Son coloring at kitchen table. Ask him “Hey bud, where’s your mom?” He points at the stairs. Walk to stairs to hear moans and movement. Up to this point I had suspected the worst but never had proof.
Knew I had to go look and catch her or she would say I was overreacting and tell me it wasn’t what I thought. Walk upstairs and hear them in the spare bedroom. Walk in the room and say “well this is awkward.” They freak out and try to grab clothes and tell me nothing is happening. I walk out to my car and have ex-buddy chase me out and tell me to hit him.
I go to my command (I’m in the military) the next day. Report him and have the command force him to call his wife that day and let her know. I am now divorced and much happier!
