If a couple is having a problem, perhaps it could be said that one of the worst things to do is ask a friend for relationship advice. People that know you are not always likely to be truthful in seeing a fault for a fault no matter whose side they are on. Often friends will stick up for only the one they are friends with, giving an unfair advantage to that person.
When relationships are on rocky ground one of the best ways to get the help needed may be consulting with a counselor or someone who neither of the two know and get help from a fresh unbiased opinion. People that are unrelated and unknowing to the couple can look at the entire situation from outside of the box, rather then inside. Those that are familiar with a couple tend to make a judgment based on past mistakes or situations.
When couples forgive one another, the mistakes of the past are to be just that, mistakes of days long gone. If a person has forgiven they need be careful to not pass future judgment on past mistakes. Unless the issues are related to abuse, cheating or some other major issue, however complaining about lifeless issue is wrong.
For example an argument is over cleaning house, if forgiveness has been given you cant bring up being sick of fighting over it, it’s not fair. If forgiveness was granted, keep it granted. Often this means people will have to stop trying to change the other one. If an individual is set in their ways and things are not changing then you are facing a lifetime of living with the same issues, perhaps if it is unbearable, splitting up before years are lost is the best bet.
Relationships are one of the hardest things to manage in life. It will mean that more often than not one person or the other will have to be the better of the two, believe me the better person varies on what day of the week it is. The better individual is the one who forgives and does not harbor or dwell a problem. It is wise to try to be the better person even if your partner is as well. Treat them as you want to be treat, that is perhaps the best relationship advice people have ever heard.
