Would you stay with your spouse or girlfriend or boyfriend if they cheated on you and swore they would never do it again?

No. I would never be able to trust them again and it would eventually cause more problems. If he was late, or I couldn't get a hold of him when I should've been able to, I would think the worst. So even if he actually NEVER did it again, I wouldn't trust him and that's not fair to either of us.
