Need to hear stories of men cheating once and never again

My husband had an online affair for 2 months in 2019. We went through therapy and he has done everything I have asked to move past it. My trouble is that I grew up with a mother who was unfaithful to my father the entirety of their marriage (15 years) and I feel like because of growing up with a serial cheater I don't think anyone can change once they have cheated. Has anyone cheated once and never again or been cheated on once and never again by their partner?
