Ouch! That hurt my heart but I 'enjoy' a bit of angst now and then.
The descriptions of the house in the beginning are what did it. They were heart wrenching but so beautifully descriptive. It hurt to think of the house that way.
I also felt that you were trying to convey that Justin understood that Brian's gesture wasn't attached to the house and that Justin understood that Brian was ready for anything with Justin. hmmm, maybe that's the message? I think I'm right but I could totally be wrong. ;)
