10. Refusing to Say Sorry Even When you are in the Wrong

On a final note, not even the most loving relationship can survive without a certain amount of mutual respect. This can be shown in various ways, but one of the most obvious is the willingness to apologize and show remorse when you are in the wrong. This shows a keen sense of maturity and integrity, as you are happy to accept when you have made a mistake and offended your partner. If sorry is the hardest word for you to say, however, this stubborn and short-sighted outlook may well end up costing you your relationship.
