girl and guy with fake relationship

my point is that if a guy and a girl are not sexually and/or romantically attracted to each other, then their relationship is fake 

and other people feel that 

so both the guy and the girl are unsatisfied because their relationship is fake 

and the more they try to pretend that they are satisfied, the more it's going to be obvious that their relationship is fake 

if guy and girl would not be together in their fake relationship, 

then girl could meet another guy and have a relationship with sexual and/or romantic attraction

and guy could meet another girl and have a relationship with sexual and/or romantic attraction 

then both guy and girl could have it better
