... .I get frustrated because I am so often there for him when he upset but I feel like he thinks he's the only person in the world that deals with sadness and isn't as accommodating when I am going through tough things. I never share this with him of course because I know this is selfish on my end however it usually leaves me feeling slightly resentful after I talk to him about what he's going through and I don't know what to do with this.
From the book, "Stop Caretaking the Borderline or Narcissist - How to End the Drama and Get On with Life," by Margalis Fjelstad":
"To let go of the Caretaker role, you will have to give up the hope... .that the BP/NP will ever take care of you first."
"Whenever you start thinking that the BP/NP will act the way you would act or the way most people would act, you have lost sight of the reality of the BP/NP's mental illness."
That is a difficult concept to accept. I'm still trying to process it. But she writes about how you can't hope, expect, or assume a person with BPD will live up to the same expectations you would have of a nonBPD in a relationship. So, for instance, if you feel like you would like to be comforted when you are going through a rough time, & the BP doesn't seem to give you that, then you can accept it & look for comfort from someone else like a friend or family member.
