Survival of marriage takes two. If one is attempting to do it, there might still be a chance. It is like the days of courtship as one will be doing the chasing of love.
I believe that failure of marriage is normally due to routine in daily life. Unlike courtship, it is always full of life. So, in marriages we can also inject some excitement once a while like courtship's days.
Take a break from your kids and enjoy moments that you had during courtship. Take life as interesting as it can be. Remember those good old days when you are in love. It can be that even though you are already married.
