The books you will read will all tell you that you should not wait to fall in love before getting married. While there is of course good reason for giving that warning , I believe that it can be in some cases taken too litteraly.The result is two peple agreeing to spend the rest of their lives together with having any true feeling for each other.That scenario will surely lead to either a divrce, or to a marriage without love.So surely you dont have to be head over heals for each other ,but its important to at least have strong positive feelings for one another.
