The solution is to eliminate the conditions that made the affair possible [your separation] and repair the marriage by creating a romantic marriage. The post affair marriage has to be recreated into something much better than pre-affair lest you will just end up with a crippled version of your pre-affair marriage.

"It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena.." Theodore Roosevelt
