Your strong and smart. Please go to Ted Talk and enter Esther Perel on infidelity and other relationship issues. Most Americans will tell you to leave him. You need to think about the entire relationship, not the past few months. Think outside the box. The majority of our society will say divorce, they maybe correct. Listen to your heart and look for remorse in him. If he doesn’t express that emotion it would cause me to really consider my options. Kind thoughts!
