While I'm not crazy about digging into the past of the 'spouse', I do find the extremes swings of Santorum's wife amazing.
....
Although they first “met” the day Allen delivered her, they reconnected when Karen Garver, then 22, called him, then 63 and a colleague of her father’s, to inquire about a basement apartment. It wasn’t too long before Karen moved upstairs with Allen.
The two remained together for six years, with Allen paying to straighten Karen’s teeth, taking her on trips around the world, and buying her a piano. By all accounts, the two were happy, even though her parents and his grown children didn’t exactly give their blessings. His profession, both according to Allen and to those who knew the couple, didn’t seem to weigh too heavily on Garver.
The couple split amicably after Karen decided she wanted children (Allen wasn’t interested in being a father again), and, not too long after, she met the man who would become her husband.
