she seriously said it was too small? how long have you known her? i have six older sisters. all have been proposed to but not all have said yes. but none of them made the decision on the size of the ring. i gotta say that i agree with Simple Man. sounds like shes more in love with money than you.
but you gotta do you. dont let anyone here sway your decision. as cheesy as it sounds, you got to follow your heart. if she is "the ONE" then go buy a bigger ring. just be happy. lifes too damn short to waste any time with someone you have doubts about.
what would she say if the tables were turned? if you asked her to get bigger breasts would she do it or would she smack you?
