Lyric correction:
"I ain't afraid of hurt; I've had so much it feels just like normal to me now".
I don't think it's about a lover who's gone. I think of it as a tribute to his grandpa with whom he was close, who has passed away. That's why he's able to be in the person's "room" in the person's "house". The person died and is "gone for good". It's terribly lonely to lose someone you love to death, knowing you'll never see the person again.
