How will I know?

I am a bit worried that I'm not more excited about getting married. Is it because I'm worried about the money, because I'm a bit stressed about the organisation thing, because when I was single I tried to convince myself that it wasn't that important and I was more succesful than I thought, because I don't want to be the obnoxious woman telling everyone about her fiancé all the time, or because I don't actually want to get married?

I really need to get this sorted before we get much further...
