She was banished here to live a life as a common mortal. Her punishment was cruel yet justified given that even though she knew all about humans, she knew nothing of living as a human. And it certainly wasn't easy starting as a common human who is supposed to be thirty two year old according to her credentials that described her identity here.
She didn't have any powers or any friends to rely on, even the 'degrees' she held was a lie which made it harder for her to teach as well. Over time she did get accustomed to it, but she also got lonely and started to experience those crazy emotions a human is capable of feeling.
As a matter of chance she met the same man once more. Having met him before and parting on good terms, they got close. Over time she fell for him and vice versa. Even his daughter, Carol became quite fond of her and thus everyone was happy when they decided to tie the knot.
