Sounds like a broken relationship, and a relationship gone very wrong, and very sad too. Sometimes, relationships are just 'impossible', with so much dynamics at play. For one, we don't know what is going on in the other person's head. Sometimes, we even live in that person's head!

If the relationship doesn't work, it would be best to find out why, and bring it out into the open and talk about it, than to just leave it hanging. If you leave it dangling, you will never know what caused the breakage, and then, you will play it over and over again in your head, like a movie. This can cause undue suffering and pain, and sorrow for a long, long, time!

Having an honest down-to-earth conversation with each other, is the best way to find a meaningful closure. Both parties don't need to end up being "enemies of the State". Both might even end up being friends after all. In the event of a relationship closure, I would still like to have that person as a friend in my life, than not having him or her in my life at all.

I can feel the pain in your poem. I can relate to it as I've been down that path before. If there was no closure, what you can do, is send good vibes to that person, and wish him or her silently in your heart, that the Universe will look after their welfare wherever they may be in their journey through life, and life can be tough. Bless them and never curse them, for what you send out, will come boomerang back towards you at another time. Love them, regardless what had happened, even if you will never see them again. Trust that both of you will be in good hands, under Heaven's loving gaze. I believe we don't meet people by accident. They are meant to cross our path for a reason.
