And to answear your question, it's impossible or very difficult to have any kind of relationship with them because they will always devaluate you at some point. What goes up goes down. After the idealization phase they will switch to devaluation mode and tear you down through a defence mechanism called projective identification. A process in which she's going to behave in ways that will coerce you to behave in the way she assumes you are going to behave. It's basically a self-fulfilling prophecy.
While projecting the bad traits of themselves onto you, they will also introject the good traits of you onto themselves and this us where it differs from normal projection. They are very selfish, self-centered, abusive and judgmental, and they project that all onto the people who are close to them. Simultaneously, they introject the emapthy, and selfless of their loved ones onto themselves. If a BPD person tells you "I care about everyone and they all exploit and abandon me" what they really mean is "everyone care about me while I exploit and abandon them".
