how likely are people who got cheated on, will do the cheating on their next relationship?

Not likely. In my experience it’s some of the worst emotional pain. Betrayal. If it’s happened to you, you’d know how awful it feels and you’d never want anyone to experience that.

If you’re unhappy end the relationship. Please do not cheat. It will kill your self esteem, self worth and self respect and lose your ability to trust anyone
