if its attraction-less isn't a relationship
if both parts of the couple don't fantasize with or without another people isn't a relationship
if any or both partners cheat on their partners isn't a relationship
unless they feel guilty or sad about it
if it's sexless or meaningless isn't a relationship
neither if it's painless or careless
you can't be actually sure that it is
unless you have been in another one
if you have doubts or trust issues doesn't mean that it's a bad relationship
if you're too much confident about it doesn't mean that is a good one
if you feel loving and loved by your partner probably can last years
but if he or she doesn't reciprocates, it shouldn't last much longer
if you don't like them both as a couple doesn't mean it isn't
because relationships are made about the ones that it really involves
and there's no rule to describe how any lovers should manage their relationships
