My Sister's Bestfriend's (21F) Bf (22M) Backed off

My (18M) sister’s best friend (21F) was in a 7-year relationship with her bc(22M). They wanted to get married. And idk much about both of their backgrounds

When marriage talks came up, the guy’s family said they’re peace-loving and worried her father would create problems. Instead of standing up for the relationship, he told her, “Let’s drop marriage, i'm scared of your dad.”

Yesterday she finally told her father about them and he completely exploded. He verbally abused her,hit her and said she brought shame to the family, and insulted the guy’s family for being slightly less financially well-off.
