Attachment to other people and beings? How does one live a life with multiple relationships (family, girlfriends, friends, pets, etc) while not being attached to them(being aware it will end eventually and therefore do not dwell in Dukkha when such thing happens)?

Thank you very much! :)
I quote from here is a short and blunt answer. This answer does not mean renounce your family but merely teaches a way to have less mental attachment to them. The problem is of one's mind, not of the world.


  § A woman came to Wat Dhammasathit to observe the precepts and
  meditate for a week, but by the end of the second day she told Ajaan
  Fuang that she had to return home, because she was afraid her family
  couldn't get along without her. He taught her to cut through her
  worries by saying, "When you come here, tell yourself that you've
  died. One way or another, your family will have to learn to fend for
  themselves."
