I think his saying "this is the last time" is him basically fooling himself, or trying to - he knows that he is weak and will give in again, and still be there next time she needs to fall on him. "years make everything right" implies that they've been together for so long that it doesn't bother him anymore, hence "no I don't mind".
It's strange though, because the lyrics to the verses are really dark, yet the melody is very perky and 'up'. Maybe he knows that the relationship is bad for him because all he does is support her, but he doesn't mind because he loves her.
