Hi, Adelfina, may I suggest some variants:
[1] ... and a life that calls for this surrender of love
[2] Wait for a while, a bit longer,
So I can bring you all my love.
[3] When we part, it's my soul that gets broken apart
I also think it's OK to use simple past on this couplet's first line
If you (ever) went away, what would happen to my life?
If you (ever) lied to me, I would believe you anyway
If you didn't love me, I would love you
