Analysis of promise?

return to me.
let me feel your tears,
let me love you,
erase all of your fears.

pull up your sleeves,
show me your scars,
scars i’ve seen you create,
let me admire them from afar.

a body undeserving
of the pain carved everyday,
let me feel your hands,
for i need you to stay.

blood on my hands
as i hold your wrists,
see cuts that go deeper
every time you slit.

breathe slow,
for i have always known.
return the blade you use to cut,
the one that cuts
right through the bone.

let me wipe your eyes,
and bandage your wrists,
keep them on,
promise me it.

bury your head in my neck
cry to me until we’re a wreck.
next to you i’ll lay until you rest,
just promise you’ll stay
for whatever comes next?
