If Ever You're In My Arms Again

In my opinion he is looking back on the past and having regrets about the way he treated her ... taking advantage of the love she gave him.

Once they separated he remembers how much she had done for him and is missing it and wishing he had done the right thing and took care of what he had and wishing for a second chance to by right by her.

A song of lost love and regretting his actions.
