I mean he expects his partner not to fuck his dad. The son is a piece of shit no way around it but so is the mc (meh) and father. The son clearly has trauma and genuinely thinks the father killed his mom and if you found your ex sleeping with you dad you would freak out too and times that by 100 if that person is your dad that killed your own mom like I act like the son too BUT it still doesn't justify what he did to mc like you literally just abandoned your partner with a man who clearly has anger issues and wouldn't hesitate to hit someone with a golf club kinda a shit move. The mc is at least a weird ass person to at most a shit person for sleeping with the dad like sir that's weird as fuck also the whole fucking dad and son and not at least telling them is ew also but y'know. I genuinely don't think I need to explain why the dad is shit.
Hmmm.... honestly I understand from your pov and maybe agreed with you but I grew up with people's whose get abandoned by spouse here to go with another partner , most of them go down the hill while only minority can take it well . For me no matter what problem between him and his father , he shouldn't hurt other person .
So I still think his father is better for his ex(mc)
After the whole drama leaving your spouse with your father what do you expect??? Is not even leaving him because of work but he cheated and leave with some girl and now you're angry because your father fu£k|ng your ex .
I support the father
