I can see you have put in lots of thoughts as well as emotions in this write. As I was reading images of titanic, Romeo and Juliet kept playing in my mind. I could also see that each stanza was written with his and her views. Very well penned with all the yearning and love afloat.

Just one thing though. This line:

I counted every second of the past threw decades

^^I think you meant three instead threw.
Also instead of writing of the past three decades, it will sound better for the past 3 decades.

Liked the read..keep penning.

I like this because it's long but keeps it's flow and also rhythm. The emotions, sadness, love and yearning are all there.
