As someone diagnosed with bpd this question kinda tugged at my heart, for a few reasons.
From my understanding, the core of the disorder is an unstable sense of self and an inherent shame or worthlessness.
Before I was treated I thought I just needed someone else, the right person to come along to love me in just the right way, being mindful of trauma and never triggering my symptoms.
I was living in a fantasy world.
You cannot expect another person, a whole person with a sound mind and stable to sense of self to subject themselves to the circus act of our lives. We can't even manage it ourselves!!
I have been in two long-term relationships, and dozens of short ones six months or less. One of the two began when I was very low and lasted a very toxic 3 years. I entered treatment during that relationship, which resulted in it's demise. I was much happier afterward.
The second relationship began after I completed treatment. We have seperated twice during the past 2 and a half years, and our relationship is currently rocky as well. But who I am in the relationship has changed.
I am no longer the girl who needs extra reassurance daily that he's coming home from work. I can breathe when he goes to hang out with his friends. I am not threatened by every waking thought of his not being about me. Instead I am the woman that validates him and myself in arguments, and I put respect over everything. Of course I lose my temper. Self improvement is a constant process.
But, to avoid hurting anyone you love, you should definitely talk to a counselor if you are looking for another person to help you :) For family members/lovers/caregivers, it's stressful and often results in a lot of resentment in the relationship!
Be safe!
