"Seek a little quiet on Christmas Eve and see the Iraqis again": Maybe they had a great time on Christmas Eve last year. On Christmas Eve this year, he wants to be alone and miss the past, as if seeing you again.

"I don't feel the same": My feelings haven't changed, but the environment is no longer like the past. It means that he still loves her, but they are no longer together. It means the same thing as "things are different"

Well, he seems to hope that your appearance can help him out of the predicament of his last love, but after a while, he found that he couldn't fool himself, and he still couldn't forget the last paragraph. So, I snubbed you.
