I did the math! If both parents donate 1,200 to the reception hall, that leaves 1,700 for me and Jason to split. So basically, if the two of us donate 850 (or $70 a month) we've got it paid for :) when my tax return comes in, I can pay at least half my portion and I'll probably only have like $350-500 left which of course will make buying a dress on top of it, a little easier. 

Thank goodness for my awesome future mother-in-law for actually discussing things with me, helping me to decide things and not being vague on the money thing. It's easier to plan when you know how much is coming from where.
