You shouldn't know that...I like her and I know nothing about her personal life except you should never date her unless you want a song written about you.
I started liking her when I accidentally stumbled across a biography show on E. She turned down a record contract with a major label that required her to "intern" with established corporate songwriters for several years before they would cut a record. Instead she signed with a start up record label and the rest is history; Free market capitalism in all its glory. Go Taylor!
As my college roommate always said, "They're all crazy, it's just how crazy are they?"
