Just leave her be. I've been in this same situation. I don't date for dating. I date for it to be "the one." Just give her time, and try to act disinterested. I know how rough it is, belieeeeve me.
We have a few other paralells as well worth mentioning. We have 7, sometimes 8 people here, until recently only my father worked. My mother and sister literally JUST got jobs. My mom has dealt with thyroid desease, lung, breast, and oral cancers. All within the last 5 years. She started smoking again too.
I've been sticking to the cree "If you're a genuinely good person, good things will come." And recently, it's begun working. You may have to put a lot of effort in, but it all pays off. You can't run away. You just have to keep pushing through with the mental toughness of a thouroughbred.
