I am indispensable to you. (Right?)

[SnarlingThroughOurSmiles]

Jealousy sits like heartbreak in my bones
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.

Jealousy doesn't eat me up inside,
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)

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?

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?

Jealousy sits like heartbreak in my bonesThroughout the poem you talk about how they are still yours and pleading them not to leave, so if they haven't left how can you have heartbreak? Maybe make that idea more clear
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. The use of the word "heart" again in this line is too much. Try using  different metaphor.

Jealousy doesn't eat me up inside,
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)

Jealousy seeps into my skin like fear:
pricked ears, verge of tears,
looking over my shoulder to see if you're near
(stay here) By saying you are looking for them implies that they are not there, so how can you tell them to stay?

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?What do you mean by "they" who is "they"?
We have something special, you'd never leave me behind.

Right?

I love your use of triplets throughout the poem; you do a really good job of continuing that structure which results in a really nice flow. However, I am confused by your change in rhyme scheme throughout (sometimes you rhyme and sometimes you don't); perhaps stay a little more consistent with that.

The title really pulls the whole poem together, as it alludes to the final line and integrates with the entire theme.

Jealousy sits like heartbreak in my bones  (just using the word heartbreak is a cliche)
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. (This whole line is one big cliche)

Jealousy doesn't eat me up inside,
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)

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.

As this is in "mild" I won't go line by line pointing out the trite phrases and the cliches, but if you removed them there would be not much left.

Love poetry is one of the most difficult types of poetry to write (along with religious poetry). It is extremely difficult to come up with fresh ways to say things and that does not happen here. The other thing is that one should never try to write love poetry when one is in love. Generally I warn people not to attempt love poetry until they have been actively writing poetry for awhile, say like ten years, and can be dispassionate about it. I mean, yeah, if you want to write the same stuff as ten thousand other people on poetry sites around the net have at it, but if you want to improve your ability, drop the love poetry and try something else. 

We all go through this, I remember beseeching Venus to inspire my rural pen that I might do whatever grandiose thing of love I thought I needed to do to impress whoever and many more just like it. All of them were terrible and full of trite phrases and beaten dead language. So, your choice. Maybe a nice poem about butterflies, everyone seems to need to write one of them also.

Best,
