Here how marriage should work in TES; first; they have to b the opposite six (gays shut up it has nothing to do with homophobe.); second; disposition of 100; third; (if opposite six you have the option of "courting" which is the same as disposition but only 5 points a day max.) which has to be 100; forth; ask for her/his hand; fifth; pay 300 septims to have wedding; sixth; marriage which will have all the people in that town of a 80 disposition or higher come to your wedding, in that towns chapel, there will be the obvious "yes" or "no" dialog; seventh; if you don't own a house you have to pay 25% of the house's worth a month. if you have your own house only 10% a month. after that there will be no divorce unless you choose, and new dialog will present it's self, along with a monthly X amount of food quests. she or he will repair one thing a day for you, have the table with food always set a day (just once a day) and will give you a potion of adventure (boost STR, HLTH, SPD by 10 for 1 days) once a month if they are a stealth type. Or give you A weapon of choice (sword, dagger, ax, bow) that has a enchantment leveled if they are a fighter type, and will repair it once a month. Or give you a ring of + 5 to a given skill if they are a magic type. And will sell a check list of your things you make once a month.
Time rewards; there would be a radiant story plot (so kinda random) quests over time played (the game as a whole); so for 5 hours for 50 hours of playing you get a quest with little story (little story through all the quests as it will be radiant driven but enough story to feel like its a real quest) then every 10 hours for 50 hours you get a quest, then every 15 hours for 30 hours a quest that finishes up the story. so this would suspend the amount of time the game would have for 130 hours with like 20 hours of game-play. so say you have character 1 for 50 hours then start a new character you would get those original 10 quests instantly and it continues rewarding you/keeping it fresh playing the game for a longer time.
IF YOU MARRY A HOMLESS PERSON YOU HAVE TO HAVE A HOUSE, IF YOU GET A DIVORCE THEY TAKE BACK THEIR GIFT TO YOU.
