I wouldn't know about mods. And can't you make your spouse cook a meal for you and give you money from their shop? Isn't that enough for you?
Yes, if I actually have a spouse.
I don't marry in Skyrim for 3 reasons:
1. Out of ALL of my characters, I've never bought a house.
2. I'd like to get money thorugh quests & murder.
3. I can cook food myself.
The only reason I WOULD marry someone is their shop. I could buy armor without leaving my house!
