three things I look for is

1. Are you listening to me? can you understand me/ my language/ my body language, my hints... responsiveness 

2.  Do you act and say the same things?  Lack of patronizing, placating, appeasing behavior- I am repulsed by that; I am looking for ...wholeness in thought and action...integrity

3. How does he treat others and how does he treat himself? Does he love life? the planet? his ownself? his health? weaker peple? children? pets? I don't tolerate brutality.  I am looking for ...kindness and dignity

then there is a strong back, good knees, nice teeth (and smile) and the ability and willingness to pull me out of a burning building if need be.
