Re: Arranged to marry at 16, not feeling right...
Whats the rush? I am a little confused here. For me the issue is not about your appearance or how you will fit into Pakistan etc..but more about why does there appear to be some urgency in getting you married off so quickly?
Marrying a cousin you dont know is not a big deal. You can get to know him.
Moving to Pakistan may not be a big deal because foreigners live in Pakistan comfortably and if you have relatives around, adjustment can be easier.
Marrying at 16 in a very short period of time? There are some details missing...either from your side or your aunts.
I think you need to find out more or share more here because there are several pieces of the puzzle missing.
