A friend is getting married pretty soon.  The wedding will be in Florida which is nowhere near me so I'm excited!
Oh really!? I have also been planning a wedding soon myself, Id really like to know a bit more about it to make me less nervous. 
Thats exciting!  People can normally get married for several reasons.  Some of these could be legal, social, emotional, financial or spiritual and religious purposes.
Id want to get married so me and my girlfriend can finally stop worrying about when or where we wanna get married lol. Do you have any clue how much a wedding costs?
I would think it would depend on how much you really want to spend.  How long did you date?  Dating is a form of courtship and consists of social activities done by couples.
Well me and my girlfriend have been dating for 3 years and we really do wanna get married, I just want to give her a huge wedding she always wanted.
Big weddings are normally fun but I'm sure it will be expensive too!  How many people would you be inviting?  That would make a big difference as well.
Wow I never thought about that but maybe 15-20 people, Most of em would be family, Do you know how much a wedding dress costs? Or maybe I can rent one? 
Marriages differ between cultures and religions around the world but in most cases I would think you would want to buy a dress.  It probably wont be cheap but I think women like keeping their dress most of the time. You could always ask and see what she thinks too.
