This is by far the biggest advice for married couples.
Picking yourselves up, dusting and moving forward comes hand in hand with patience. And this is what many married couples are not willing to wait for.. In the end breaking up happy marriages and the children get affected with the separation of the parents.
Your wife as you've said knows she deserves much better but she appreciates the best you provide. This is what we who are in marriage ought to learn. Am glad she's by your side through thick and thin. Your marriage will always continue blossoming with love.
