Lyric discussion by quietwar 

sorry eyes cut through the bone you make it hard to leave you alone (She's done something or said something wrong then apologizes & he always forgives her)

leave you here wearing your wounds waiving your guns at somebody new (he's going to finally leave her in the midst of her fury or pain & she'll find somebody else to direct it to)

i'm tired of fighting fighting for a lost cause (hes tired of having to defend himself and tired of fighting to keep her)

theres a place where you are going you aint never been before no one left to get your back now no one standing at your door (She's left and he won't be the one to be at her doorstep like he's always done. he cant be there for her anymore)

baby your a lost cause i'm tired of fighting i'm tired of fighting fighting for a lost cause (he cant fight to keep her anymore, its hopeless)
