It's a good poem. It does a really good job of describing a manuplative stalker. 

The line "You got here too damn late to be open"  stuck with me

not a criticism but a suggestion certain lines don't fit the rhyme scheme (if there is one certain line rhyme some don't )  if they rhymed it would be the cherry on top.

I'll give it another shot to see if it expands. Thanks so much for the feedback!

It was set up well so I will say after. I immediately wondered what happens next. Does the selfish persons cycle keep going? Does it stop? Does it just stop with you/the author? That’s at least what I found asking myself at the end

Really? Thank you very much. You think it needs it before or after, story wise?

I have to be honest I wish it kept going. It spells out a story and I felt like wanting to know more. Definitely enjoyed your writing.

I know it's you
