actually in this case, you kinda don't, she can say whatever she want, the important is she sticking around, woman will talk a lot, most of time means little to nothing, its her actions its important, a woman interested in you will stay with you for years even if she bug you sometimes about marriage, but the moment she do this and leave you know she was not that interested and invested on you, with is for all reason the why you didn't marry her.
also I did read this before and agree, to marry a woman she need to prove she deserve it, and that is not she asking, is she proving she will be there to help you, will add to your life,
@dustmuffin know she wouldn't, he was aware she just wanted a sucker to pay the bills, hence why he would never commit her "wishes"
also guys need to understand the main reasons for marriage for woman, social status, security and money. woman love to compete with everything so don't doubt if they compete not only on how desireable they are with they "friends" but also who would have a happier life, if they have some friends marriad and say they are happy, jealousy will kick in she will try to compete, security is a given more people in her household more secure she will feel about, reason why men are more interested in house and farms/ranchs, and woman are more for apartaments, its all about security, and I hope I don't have to explain the money part
in this case there is nothing to feel back about, she proved to you she was not a keeper and are easily replaceable
