That is only one perspective on BPD. It's not a very kind one towards people suffering from the disorder. They tend to overlook that we don't set out to use people and spread misery and distress. We are the way that we are for reasons that make sense, and we can overcome those patterns. BPD does make relationships difficult, and if you are going through relationships and ending them prematurely or noticing patterns that hurt you or someone else, it might be wise to try to give romantic relationships a break for a while and work on your patterns while building other kinds of supportive relationships - then go back to it when you are ready. Yes, it takes time, and that isn't easy to hear. It's worth it though.
