I really like this poem, but the first line doesn't flow so well.
"Why you need me again?"
I think I would have gone more of
"Why do You need me again?"
or
"What? Do You need me again?!"
Probably the latter.

I love the final verse, because I believe we all have had that one toxic love in our life.
The one You have to completely shut down for a while, to keep them from getting back into our hearts.

Over al I gave You a 5. I felt that You did portray Your emotions here, and it was not badly written. But I would like to see more metaphors, and symbolism in Your poems. It really would give them a catchy edge.
