The MC is an idiot who should speak up and say. Um, I’m not a bought fiancé. I got hired as a live in house keeper. You can’t marry me against my will to an abusive asshole! I’m calling the police. (He even still has his freaking cellphone!!!!)
Abusive asshole, even if the idiot MC married you, raping your ‘wife’ is still rape. Go die in a fire! Just because you ‘love him’ or whatever those possessive feelings are, you don’t get to abuse your spouse.
