I think he said "Thanks for everything" because he left the main character. Maby it was too much for him? He didn't leave for germany?
And for the lover (sorry I forgot the names). He seems like someone who manipulates people. At first I thought "mabye he is some psychology Type?" And then his reactions when he was asked of his previous lover....
I don't think he is that good one to be around
Really sad that you arent translating Amy further.... but still think you!
