Hi there, so sorry to hear about your situation. I can relate at the shock and gut wrenching feelings when I discovered my wife's affair. You will learn and grow and become stronger through all of this.
That said, I would highly recommend episode 76 of the "Relationship Alive" podcast. It is titled "Healing from Infidelity" with Michele Weiner Davis, the author of Divorce Busting. I really learned a lot listening to Michele and catching her tone in addition to her thoughts.
Work on detaching and go slow. Good luck.

It is not things that bother us, but the stories we tell ourselves about things.
