On accounta she's such a nice girl.
In Darryl she saw an older man who would take care of her. Surprise! Doesn't want to marry again, not so hot at twice her age, and not so much money (lost the house). Travis...looking for a Mormon wife (convert!), better looking and younger than Darryl, at the top of the company (she got to go to the big party with him first night!), and with a whole bunch of earning potential. Just one thing...he saw her for what she is...a ****. She wasn't marriage material. But he was a 30 year old man who...shockingly...wanted sex, and she was ready, willing and able.
