Would you let your parents guilt you into having a wedding that you don't want?

My mother is telling me that I have to have a wedding so that my father can walk me down the aisle because one sister didn't let him and the other's crazy mother (his ex wife) was there and he didn't want to deal with her and her crap. I don't want a wedding because I have social anxiety and can't stand having people focusing on me regardless of whether they're family or not. I just want to be married at the courthouse because it's small and simple and you're saving money. My mother told me that if I get married and don't let my father walk me down the aisle that I better just leave home.

Side note: I've tried moving out before but they dragged me home by guilting me. They're really good at making it all about themselves and not caring what you want, so I have no backbone to stand up to them.
