It always breaks him a bit, when she says it. He's not sure what he's done to deserve it. And very sure that he's not worth it, but he can't give it up.

He wraps his arms around her as they kiss, and holds her as close against him as he can. If he didn't already have a reason to return, this would give him one. And right now, he's not sure how to define them outside of this grief - but there's hope, maybe, that it can happen. He's willing to try.
