^I agree, but not with it being to complicated, nothing is ever to complicated to explain, so I shall explain!
I think we all know the first part is him finding someone he loves,.
The second talks about faith, she has faith he will get better and it hurts him because he doesn't think so.
The third is him wondering if hes strong enough to and him dragging her down with him, but then he remembers you would be helping.
And so he has her life and his own in the balance but he doesn't want to get rid of her.
