all good but the first line- love and throrny rose is overused, too common a metaphor. Otherwise I like your poem. It has great energy. (no need to cap the Present and Past).
I was thinking about this song lyric which is quite strong as a poem, and also quite strong as sung by Freddie Mercury. Check it out after you read the poem, https://www.youtube.comwatch?v=c3X6KtQ7nxQ

"Love Kills"
(from "Metropolis" soundtrack)

Love don't give no compensation, love don't pay no bills
Love don't give no indication, love just won't stand still
Love kills, drills you through your heart
Love kills, scars you from the start
It's just a living pastime, ruining your heartline
Stays for a lifetime, won't let you go
Coz love (love) love (love) love won't leave you alone

Love won't take no reservations, love is no square deal
Hey love don't give no justification, it strikes like cold steel
Love kills, drills you through your heart
Love kills, scars you from the start
It's just a living pastime, burning your lifeline
Gives you a hard time won't let you go
Coz love (love) love (love) love won't leave you alone

Hey love can play with your emotions
Open invitation to your heart
Hey love kills
Play with your emotions
Open invitation to your heart (to your heart)
Love kills (love kills), hey hey, love kills (love kills)
Love kills kills kills kills
Love can play with your emotions, open invitation

Love kills, hey, drills you through your heart
Love kills, scars you from the start
It's just a living pastime, ruining your heartline
Won't let you go
Love kills, hey, drills you through your heart
Love kills, tears you right apart
It won't let go, it won't let go
Love kills, yeah

I liked the first line, works perfectly. A wonderful write. One could ponder with this truth, as we all or almost all, have experienced this seasawed merry-go-round labeled love. I would not change a thing here. Nice writing.
