"...but they measuring themselves by themselves, and comparing themselves among themselves, are not wise." (2 Corinthians 10:12b). In my quest to know how to succeed and enjoy a lasting relationship, I 've discovered that one of the things to avoid in your relationship/marriage is comparison. Trying to compare your partner with your friend's partner or other people is one of the mistake that can destroy your relationship/marriage. We are created differently and unique in our different ways. A lot of break-ups/heartbreaks are results of comparison and disappointment of some expectations. Some ladies who had been blessed with the right man(though in his growing state to being great and wealthy) had broken up with him just because they compare him with their friend's fiancé (who is rich & probably drives a car) and wish they also have a man that will be rich (ready-made) too.
A lot of brothers who had equally been blessed with the right sister(godly, submissive & dresses decent) had broken up with her because they compare her with their friend's babe(who dresses loose and do all sort of things with her man) and wish they can also have such babe too. Apostle Paul said such people are not wise. Accept and appreciate who God has blessed you with and make your relationship/marriage work out. Don't compare and try to change your partner. Your relationship is unique just like you are unique. Things that work for A may not work for B in relationship. Comparison blind your eyes to see the goodness in the man/woman God has blessed you with. It makes you endure instead of enjoy. Relationship/Marriage is not a competition. So stop all the comparison. A lot of people face challenges in their relationship but u won't know bcos u always see them smiling and laughing together. Try as much as possible to celebrate your partner.
