My sister (22f) was supposed to be getting married this year but she pushed the wedding back another year because my dad and stepmother refused to let me (17m) be her man of honor when she didn't ask our step or half siblings to be bridesmaids or groomsmen too.
My dad confronted my sister about asking me several months ago and told her it wasn't right. He told her she HAD to include all of us or none of us would attend the wedding and he would stop me going too. She told him she was not going to give into him. He said she shouldn't prioritize me over siblings that are younger or just not biologically related to us. She said they (him, his wife and the other kids) were only invited so she could have me there and since he was imposing such an awful rule she was just going to move the date, I'd be 18 and able to choose so she didn't need to invite the rest of them.
The new date is next year and I will be 18 and I'll already be moved out. My dad and stepmother are pissed she actually went ahead with her plan and that I still plan to be her man of honor. They told me I cannot and should not do this. That I am putting my other siblings feelings at risk and making them feel rejected by two of us. They said my sister was making me choose between her and the rest of my family and I should not choose her for that reason. I told them I would always choose her and they were not going to make me say no.
This argument continued and I ignored it for about two months but the other night they told me to sit and talk to them and they said my other siblings had noticed what was going on and I should feel bad about that. I told them I didn't. They told me I have five other siblings and shouldn't hurt a relationship with them a relationship with one. I told them I didn't care what they say, I'll be her man of honor and they won't stop me. So they need to just let it go because they are making the countdown to my 18th birthday a bigger deal.
They said I'm being hurtful and I'll regret my decision to burn all these bridges in 10 or 20 years. My dad told me I might think mom would be proud of me for standing by my sister but he believes she'd be disgusted at the two of us for not making room for the growing our family did after she died.
AITA?
