Realize the person who did it is the devil and there's only one devil in the world.

I don't fear someone else cheating on me. (I'd just walk out the door and never return.)

I fear me doing it. The unthinkable became thinkable, when someone did it to me.

It'll never happen again. No more relationships.

For me the fear never truly went away. I just tey to suppress it as much as I can. Being cheated on is a hard thing to get past.

I didn’t. You can move on from something but deep down, those thoughts and suspicions are still there, even if I don’t voice them

I never have because pretty much all my partners have cheated on me.
