Does renewing wedding vows strengthen a rocky marriage?

Eric, if it's just not there to begin with, I don't feel redoing your vowels will help things anyway. Love pure love is the name of the game, the name of it all. Without love you don't have much. IF by some chance the two of you feel it WILL be of help, then by all means do whatever you feel will help it along. We're all different, what works for some doesn't for others & visa verse. But before you make up your mind for good, talk it over with your wife & see how she feels about it. It just may be the thing for YOU, no one can truly ans. that but you two...the best to you...:)
