May i know how did one actually forgive your parnter infidelity and how to move on?

I couldn't forgive my spouse. So we actually separated because of it. I am not married to someone else and never been happier. Not saying that's what you should do. But it worked out in the end for me. That said, we didn't have any kids in the other relationship and I am financially very able, so I didn't need someone to support my life
