Nah I don't agree. It's like the phrase "a leopard never changes it's spots", as others have said that's a too narrow, black and white way of looking at it. Someone can absolutely make a mistake once and not do it again. There are some compulsive cheaters who just lack an ability to commit to someone but they're not representative of everyone who's ever been unfaithful.

I'd find it hard to continue a relationship with someone who cheated on me but not because I assumed they'd do it again, but because it's the ultimate betrayal of trust and I'd have no interest in being with someone who ever felt the need to stray (even if I felt confident they wouldn't do it again).
