Pierce the Veil - Bulletproof Love Lyrics Meaning

I breathe you in with smoke in the backyard lights,
we used to laugh until we choked into the wasted nights.
It was the best time of my life, but now I sleep alone,
So darling, don't, don't wake me up, 'cause my thrill is gone.
(Say I'm wrong)
In the sunset turning red behind the smoke,
forever and alone.
Yeah!
(he can see in the distance that the relashionship is ending and he was dreaming that is was gonna be ok but its not and hes dreaming)

You've gone and sewn me to this bed, the taste of you and me
will never leave my lips again under the blinding rain.
I wanna hold your hand so tight I'm gonna break my wrist,
and when the vultures sing tonight I'm gonna join right in.
(hes saying he kows the relashionship is ending so hes trying to hold on to her)

I'll sing along, oh
'cause I don't know any other song.
I'll sing along,
but I'm barely hanging on.
No, I'm barely hanging on.
By the time you're hearing this I'll already be gone,
and now there's nothing to do but scream at the drunken moon.
(hes saying he'll play along even thought he knows shes cheatingcus hes bin cheated on like all the time so he knows no other way to have a relashionsip)

This isn't fair!
(No!)
Don't you try to blame this on me.
My love for you was bulletproof but you're the one who shot me.
(hes saying its not fair that shes cheating but shes saying ilove you but your killing me )

And god damn it, I can barely say your name,
so I'll try to write and fill the pen with blood from the sink.
Woah oh
But don't just say it, you should sing my name.
Pretend that it's a song 'cause forever it's yours,
and we can sing this on the way home.
(just tell me you dont wanna be with me instead of cheating)

I'll sing along, oh
'cause I don't know any other song.
I'll sing along,
but I'm barely hanging on.
No, I'm barely hanging on.
By the time you're hearing this I'll already be gone,
and now there's nothing to do but tear my voice apart.
Nothing to do,
and scream at the drunken moon
