Generally many people find it very difficult to accept their mistakes if it is pointed out to them.
They will try in every possible way to justify the wrong. If we adopt this manner we may please our ego, but we will not improve ourselves in anyway, and will only affect our marriage and relationship negatively. On the contrary, if we calmly consider what the person has said instead of going on the attack, this will save us from many futile arguments and fights. Over time we will become better people and as a couple in marriage, greater understanding and love will be created.
May Allah Ta‘ala help us to accept our wrong rather than trying to justify it.
