Every positive thing done in your marriage should be counted. Don’t just dismiss a positive act because “that is what spouses do for each other” or “it’s such a small thing”. Every small thing adds up to a wonderful relationships.
And don’t take anything for granted. You are blessed that your spouse does ‘what they are are supposed to do for each other”. Some people don’t have that.
if you start counting the positives rather than discounting them, they will no longer seem trivial to both of you.
