I'm cheating on my husband and I cannot stop.
Do you think about your husband when you are with him?
I always think about my husband's face when he is tickling me.
Cheating on someone is something you have come across as fine to do. This is a bad way of thinking, things will get messy. Stop the affair or get a divorce, make the best choice for you all.
I don't think I can stop at this point.
Don't be surprised when he finds out and wants to leave you. What you are doing is extremely hurtful. What happens when your new fling wants something more serious?
