I just think it's weird. Girls should never propose to a man, because what if the man you are about to marry, turns out to be the wrong guy? Then you're screwed. By having a man propose to you, it lets you know that he is fully ready and that you can trust him.
if she wants to, but I am against surprise proposals, marriage is serious and should be discussed. It isn't fair by any means that one person in a relationship (usually the man) gets months of saving up money for rings and putting together some elaborate show. While the woman is left with only a matter of minutes to either say yes or no, sometimes leading them to say yes out of not wanting their man to feel bad after all his hard work.
