Does everyone deserve second chance?

Ive always been of the mind that everyone deserves a second chance if they have learned and changed from their mistakes. Learning from your mistake means that you acknowledge it and are willing to take responsibility for yourself. Changing from your mistake is vital.

Should I give my cheating wife a second chance?

If the perpetrator offers heartfelt condolences, proclaims his or her love for you, and wallows in pity when they cheat but then do it again, it is not a good idea to keep giving them second chances. You should not have to put yourself through more hurt and disappointment because of their false promises.
