If he isn't a rapist, my bad. I read these few chapters, and the context clues seemed like he was. If not sorry for the confusion. However, being physically abused is very close to that, and the way our sweet boi reacts, it feels like it is something more. Also, if you notice his body language whenever that guy is around, it just screams that more than beatings happened.
I just want to inform you, he is an abusive rapist. If you sympathize with him, you would become one of his victims.
You would be mentally tortured, and receive the minimum affection necessary for the relationship to continue. If you want anything, or try to set boundaries, you become the bad guy. If you stand up to them, they become volatile.
This creature in human's clothing deserves no sympathy, and no second chance. Time does not heal those who enjoy being a monster.
