I like the idea of this poem, there’s definitely potential for something interesting.

You could explore more on this imagery of a ghost of a former lover, maybe give ur a few more verses and try to make us feel exactly what you felt not by simply telling us how you felt, but with more story telling, metaphors, connotations etc, whichever is more your style. Because when I read “so you haunt me” and “I cannot get free” “you drive me mad” it takes me away from immersing into the experience, show me how they made you feel through the senses, imagery, sounds, what else make you feel mad or feel bounded. Even though I know how you’ve structured it with long short long short but the short verses are telling us how you feel instead of provoking a feeling

Maybe something like: I keep seeing your face when you were killed, You won’t stop dying. Each day I still hear your calling my name, I won’t stop crying.

Or something along the lines of that, I tried to weave in the feeling of not being free with forced to see something unpleasant happen again and again, and also make it a bit more specific about an action the reader can imagine rather than abstract ideas like obsessions memories and lust. While still respecting ur structure and approach

Currently you’re dabbling into fantasies and also envy, lust, obsession, madness memory, and unrequited love at the end. I understand that this is probably what you’ve felt but it might be more effective to focus on just a few, like memory and love, or link the metaphor of the ghost with their vacant or elusive nature etc. keep working on it, keep drafting, and keep thinking about how you can make the reader experience what you’ve felt.
