If you describe a cheater, it's a person w no loyalty, low morality, & no ethics. They rob u of your feelings, peace, & happiness. If you're unhappy, just leave. But cheating? That takes planning sneaking around, lying, hiding. It’s a deliberate choice. When a cheater says, "I cheated because of u, because of how u treat me," they're deflecting blame for their lack of morals and loyalty. It makes no sense. Cheating is always a choice, and it's on them.
