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.
