Keep him suffering! Think of how long he did that to you!
I don't care if he lost memories of you because they were the most precious things to him, he needs to suffer a bit for all the pain he has caused you with his own amnesia!
He's getting what he deserves!
...Though, just another chapter or two will do. Then you two need to make up and finally be happy again. I can't take much more of chapters of this awful friction between them.
