I dont understand girls?

ok so i live in California and a girl thats a friend of mine lives in NC. we talk alot online...heres the deal...this girl is like really really hot....but shy and stupid...and well christian...she says that she is done dating guys that dont fit her idea of a husband. so she is a nanny and when she is not working she really doesnt do much cept go home and get online and talk to me. anyway she went to a party today that she has been talking about for weeks...yea was so excited about going she went on a slim fast diet just to wear somekinda jeans...so she straves herself for like 2 weeks. it turns out that this party is more like married couples drinking eggnog and playing pictionary... the reason she was so excited is she tought this guy would come who she only met once..so when i talked to her before the part she was all bumbed bc he most likly woundnt be there....and i told her to get his number and call him and tell him to come...of course she said No Way...and went to party .......
