…living in a luxurious way with  good understanding
  
…living in a slum area with good  understanding
  
…living a ‘good life - together’ 
 
…living a ‘bad life - together’ 
   
…living an ‘ugly life - together’ 
 
…one ‘dominating’ and other ‘obliging’ 
 
…living for each other 

...living together

in a married life ?
