The way I look at it I'll never see her again after she leaves unless she webcams and quite frankly I'd rather have spent my money on that, so I still want her to stay as long as possible albeit in an increasingly vain hope.
However if the last 30 days she stays are like the most recent 15, without the massage when I did get some nice shots even in the fucked up lighting, then there really is little point in her being here, and I get a month of my life thrown in. I really feel conned.
