This poem flows so elegantly it gives such strong emotions I love your choice of wording and the ending was just magnificent.

Very beautiful and hauntingly sad.

'Cuz now that you're gone
the half of this heart is missing too..
Break these walls,
take me high and away with you...

I can relate so much to these words. The pain of losing one you love is the worst pain there is.
Excellent job!
Take Care
