Why do relations break?

Why do relations break?
Why do we feel that love is fake?

When ego and pride
rise from the place they hide,
suppress our true feelings inside
and spread themselves wide

We see things with our eyes
rather than with our heart
that leads to illusions
and throws the actual truth apart

We act crookedly wise
never try to compromise
We do not try to forgive mistakes
as if we are perfect in our ways

We will not accept the person
the way they are
We try to change them, mold them
according to our wishes, that finally leaves a scar!
