Just want an opinion on if I should go on with this...

Your everything to me living
But even more to me cold
Constantly fighting and crying
It just keeps getting old
most definitely
just write loads of lines on the topic, find a melody for the lines to be sung at
and change the words from there if they don't fit the melody

from what i'm understanding its about a relationship that both people love being in, and love each other. but the fighting and arguements is tearing them apart.
just keep writing!
