Oh, alright. Well then, we should get rid of 一緒に. I thought that you were with her in 青森, but now you were in the US or something. The reason that I used あなた twice was because of what I just said, and it seemed to be used differently in the second part of the first phrase, so I thought it needed to be said again.
Alright, revised version after having been enlightened: 僕は青森県にいた時よりあなたに近いのに、まだまだ遠いよ。
