What is it about her that you miss? Are you being realistic?
One of the biggest things I miss is the ability to hold an intelligent conversation about things I am unfamiliar with. We both have rather high IQ's, but she is intelligent in reading/writing/creativity and I math/science. However, should we start again I realize that she needs to be the one in control of all conversations - which is fine.
There where times in our relationship where I did the right things for a BPD, of course not understanding the underlying issue - eventually it would boil over. During those times, she could be the most fun/loving person to be around.
During other times, she would get physically and verbally abusive. Again something I feel ready to deal with now, understanding where it comes from.
There is also a wild streak in her that was never explored during our relationship. Now I know that exploring that will actually increase our bond.
I had attempted to fix her. Seemed like she was getting close during the end, but also why she probably pulled away (plus an enabling psychiatrist.). At this point she probably wont ever be "normal", everything was undone. My ex has a huge problem with "forgetting" what she has done and the psychiatrist believed her story without question, labeling me as the bad guy and even worked to cause our break up. ExBPD is now looking for a new psychiatrist, she has labeled her current one black - since all the advice she gave her has backfired. ExBPD is now coming back to me as I am the only one who ever gave her advice that panned out.
On the other hand, the appeal of a normal relationship does seem nice at this point. But it also seems lacking.
Figure at this point, between the two of us we make enough to party/go out 3-4 times a week. That may be all we ever do, but it could be one roller-coaster ride of a life. Hate to put it this way, but I know how to control her - always tried to fix her before and never wanted to control her, but at this point might as well enjoy the ride and do what I have to to enjoy it.
