Long term support needed

Hi, I have been searching for a listener who will help me through my issues I am having with my 23 year old son and his girlfriend. His girfriend basically used me to gain my son's attention and lured him away. It is a long, complicated story, been going on for 3 years, I have been depressed and am deeply hurt. Short term listeners are not working out well. Is there anyone out there whom I can talk to about this?
