Step 3: Condition them to do things for you. If they do reward them.
Step 4: Continue Steps 2 and 3. When they do things for you continually. Give rewards based on random chance.

Step 5: Relocate them to your place of living. (If their place is better move there.)(Why this step? It makes you an irreplaceable part of their life.)
Step 6: Shape their personality to your liking. (It can't completely be against core values. That takes far more time.)<REMEMBER TO KEEP DOING STEPS 2 AND 3>
Step 7: At this point if they agreed to move without resistance you can now ask them to do things that are more out of their comfort zone.
Step 8: Have them Create works, books, paintings, cloths, pottery, China, poetry.
(Make sure to help them in the process. You can make them stall or move foward with just your will.)
Step 9: You now have the perfect wife and fuck buddy.
