The cousin ended Her life because of Her desire and attempt to be completely with Her lover (Her own father) ended disastrously for both girls and She was overcome by grief.
Other than societal proscription of their desires, there was NO reason for these two bondings to be such disasters.
Hopefully, the fellow I shared time with and his daughter fared much better. I do know he has a limited presence on the Internet but I don't look to contact him. It still is unknown to me if his daughter is with him or not.
