Dealing with betrayal

How do Leos handle break-ups, especially being cheating on. I'm struggling with it.

Hey, I'm here now! 😉 Sorry, I got in a bad motorcycle accident.

To the op, cheating is the worst betrayal. I don't think I'd ever forgive or forget it because I don't buy the,
"It just happened..." excuse. Things happen because you want it to or need it for your ego but either way,
the relationship was not important enough so for both the cheater and cheatee, it's best to move on.
