I specifically mentioned "basis of European marriage" which comes from the Romans as they were the first to introduce the concept of "consent" from the woman - i.e. the Woman had to specifically agree to the marriage, this is where the "I Do" comes from in the Marriage Ceremony!
Prior to that (I think it's valid for most cultures and relgions?) marriage was a pure business deal where the women was "contracted" or "brought in" on a exclusive "deal" basis to look after the household and breed, simple as that really! The concept of love did not enter into the arrangement - the Greek essayist Plutarch calls love a "frenzy" and believes that "those who are in love must be forgiven as though ill"
