If a simple apology even when you are right can save your marriage, I think that would be the best thing to do.
Keep aside the ego and carry on with your married life. Don’t invite tensions which can be easily avoided.
This would be my sincere advice to you.
I know advice is like castor oil – easy to give but difficult to take. Even so, castor oil has immense medical benefits.
Choice is yours. Life doesn’t offer too many chances to everybody.
