Here’s what I do for spouses to give them more life. I use Follower Live Package to make my spouse a follower. Then I use My Home is Your Home like so. I assign my spouse my house as their home and my bed as theirs (redundant but I do it to make sure it all works.) Then I take them outside and assign them a spot to work during the day. Usually this is the market so it looks like they are wandering around doing things all day. The time’s I’ve married Isobel, I tell her to work in area where the forge is. As she’s near the forge idle point, she happily works the forge along with whoever the actual blacksmith is. Her inventory is still generic, but it’s a little more lifelike.
THen you can dismiss them and they’ll have this new, more lifelike AI package. NOTE – you have to reset all this if you move your spouse! Otherwise, you’ll find them wandering to the old spots you assigned them
