Personality:
What do you appreciate most in him?
What's just ok?
What aspect of his personality or lifestyle did you see change since being with you?

What's his worst feature?
Abilities:
What does he do best?
And what does he do worst?
If you could get three wishes on his behalf what would you wish for?
