I am indispensable to you. (Right?)

[billy]

i like the title the barb is dictates what is coming.

the first line is the main line of the poem heartbreak isn't usually the bast of words to use in a poem, whereas [jealousy sits in my bones] works much better on it's own
watch out for line that water down a stanza. i'm hoping others will help with their feedback. use as least words as possible to get the poem to the reader then if needed embellish with more imagery; make the feeling of dependency show more as an image than question

Jealousy sits like heartbreak in my bones would something other than heartbreak work better?
The same hollow cold
The same sour ache
The same desperation
when you can't let go
but your heartstrings are yanked so hard they might break. use metaphor of simile for effect and imagery. [they break like...]

Jealousy doesn't eat me up inside, big cliche, these also [usually] weaken a poem. be original when ever you can [which should be almost always]
jealousy twines into my veins like vines,
jealousy is mine, jealousy won't leave me
don't you dare leave me
all you need is me
(let's be real, you don't need me) as the reader i feel beaten to death by jealousy. sometimes subtle works better and less is more. the 1st 3 lines; are they really needed?

Jealousy seeps into my skin like fear:
pricked ears, verge of tears,
looking over my shoulder to see if you're near
(stay here)

Jealousy is me begging you please on the inside
Don't forget me, don't leave, what would I do otherwise?
They mean more to you than I do, but I mean something, right?
We have something special, you'd never leave me behind.

Right?
