Respect and Love are integral components to every marriage. There are no two ways about it. Of course the feelings of love are going to deepen and mature after marriage, but you need them before as well. If a couple is rushed into getting engaged (Nu, its already been 6 dates!) that can only backfire. You can’t help feelings that aren’t there, if you are willing to invest the time to see if they develop, kol hakavod.
I can get along with a lot of people, that doesnt mean I have to marry them.
