Hi there, I am typing this as a way to gain insight from a more neutral perspective. I have asked this same question on a for lack of better term "anti" BPD site and now I come here looking from a BPD sufferers perspective.

How "easy" is the discarding process for a BPD sufferer? 

I ask because I was recently (2 months ago) discarded by a "Quiet" BPD sufferer. It all came so sudden that it basically felt as if she never truly cared or loved me as she declared for the 2 years we dated. The last 4 months we became distant in that she prioritized other things and I being the considerate bf did not bother her with my thoughts as I was of the mind that it was mostly due to school stress. She would often apologize for not being able to provide what I deserved and how crappy of a gf she was. One week she loved me dearly, then next she's "not interested in a romantic relationship." Anti BPD sites say that BPD sufferers are heartless, incapable of loving, emotional vampires, who only use people until they are no longer needed, and honestly right after the breakup I honestly felt that way too, but I was also super emotional with the suddenness of it all (spiraled), but Ive always been one to look deeper and from all angles so here I am. Any insight would be greatly appreciated.

We never argued, she just always felt bad for not being able to provide for me physically or emotionally. She hated her crowded home, hated her coworkers, stressed from school. That said it almost feels like she just gave up and didnt want to fight for our "love." She went silent after sending me a love song reply to me asking her if we could talk on the phone at least. I tried reaching out that first week but nothing, so I havent bothered her afterwards.
