Wow - coming up on 7 months N/C. At the six month mark "strong craziness" emerged but that has passed. I see similarities to my recovery from drugs and alcohol - milestones / chip days at 1, 3, 6, 9 months in early recovery are risky times.
The relationship was very much like my days in cocaine addiction. It was good when I had it ... .  terrible when I didn't. I have abandonment issues (core stuff from my childhood) and when she would "split" psychologically (love to hate in a nano second) and then physically (leave) it was like running out of cocaine but even more painful. Then I would go into "getting her back" mode ... .  like calling the dealer. Then she would reappear and "All would be well" ... .  until she would split again. This was a weekly to monthly cycle. I lost 25lbs over a year ... .  my soul felt like it went through the wringer ... .  all the juice was being squeezed out.
So today I am a grateful recovering addict, alcoholic AND BPD sex and love addict. Why am I grateful on all these recovery fronts? Because recovery has led me to understanding and loving myself more fully. I am finally growing up (at 57 yo 

). I am perfectly imperfect.
She was my teacher. "When the student is ready the teacher will appear". She did and then left ... .  I learned that I can not be in a r/s with a person with a serious mental illness (or addiction). I have a "rescueing" tendency but I cannot love someone back to mental healthyness ... .  it is impossible. In the attempt I abandoned myself (especially my inner child) ... .  I will never do that again. If it happens, my next relationship needs to be inter-dependent ... .  not codependent.  I am giving myself a good year before considering this. I am enjoying casual dating and have met some lovely women. I am open about my need for healing.
Last night I stumbled apon this new song by Donald Fagan. It really speaks to me and I hope it speaks to you.
