I'm a firm believer that we all have an obligation to ourselves - and those with whom we have relationships - to learn from our mistakes. If we can learn from other's mistakes, all the better. Recently, I took a lesson I read about to heart. A woman talked about how her single friends might have ruined her marriage. It wasn't that they set out to sabotage the relationship, nor that she had a physical relationship with any of them. But she admits to what I would call an emotional affair and spending too much time with members of the opposite sex. And she says she loves her friends, but she knows now that she has to love her husband more. Also, she has to make her husband her number one priority. This is a mistake I've seen far too many people make. Often, people get married and continue to put their friendships or family of origin ahead of their spouse. Sometimes, they have children and forget to tend to their marriage. This can lead to lots of marital problems. What do you do to prove to your spouse that he or she is your top priority?
