Bobbie,
Nice stuff here....Though/This - you could do without either word if you choose just leave it at-War's or war is so hard to explain.
The jump to the wedding didn't stump me I thought it was an obvious thing --but i can see why some might have said that - since the whole start is about him going off and her worrying.
Could possibly say
Two hearts reunited with joy
Overflowing as they wed ???

Our turn on earth is all too brief - works better for me on that line.
