Throwaway account because my boyfriend doesn't use Reddit, and I'm asking on his behalf.

Reddit, please help me out. Here's the story. My boyfriend's parents are getting a divorce because his dad has been cheating on his mom with another woman via the Internet for over a year. They broke the news to my bf the day before his birthday. I know, right? Pitiful. His dad is a scumbag, I've never liked him. My bf doesn't like his dad either.

Anyway, his dad called him today to tell him that he and his new woman are getting married in JUNE, and they asked if we could go. Of course, my bf absolutely does not want to go, and since his father doesn't have any friends, he'd probably end up being his best man, or at least one of his groomsmen. But here's the catch- his father pays his phone bill, car fixes, and car insurance, and my bf is afraid his dad will cut him off financially if he doesn't go (although my bf pays his way through school, pays his own rent, pays for his food, lives in a whole other state than his parents, manages to support himself). Is that irrational for him to think that his dad might cut him off if he doesn't go to his wedding? Has anyone else been in a similar situation?
<bot>: Bf's dad is a jerk and he's getting married to woman he cheated on his wife with, wants his son to go to his wedding but he doesn't want to go, afraid of being cut off financially.
