Will smoking save your lung? How many people have fallen into this pit, and lived to tell their tale, without a scar on their lungs? How many husbands have cheated and lived to tell that there is no scar in their marriage? You mean, if there is something wrong with my lungs, i need to try smoking so that i can reevaluate my condition and give my lungs a second chance? Will that help? If you don't see any positive outcome with my analogy, then you can't see any positive outcome with the idea as well. How many husbands here can bear the thought of getting back to your wife who's been humping and sucking other guys' cock? How many wives can bear the thought of their husbands sleeping with another woman? where is the second chance in that? SEX is a very ADDICTIVE habit. Once you get into it, you're trapped forever. Once you started having an affair, there's no chance it will save your marriage. The best thing to save your marriage is to communicate. Instead of having an affair with another woman, start the affair with your wife. Learn to listen. You say more when you listen more.
