I had to really learn that after that breakup...I felt absolutely worthless, like no one could or would ever love me. to regain my sanity I had to realize it was not due to my intrinsic worth that he made that choice, he made that choice because of who he is and where he's at. Same with you. Relationship with someone with personality issues can really make you question your self-worth, but it's not the reality.
And as for understanding your vulnerabilities and seeking to heal...100%. That's what this relationship did for me. Before, I thought I just fell for the wrong guys...this relationship was painful enough that it made me start looking at myself and recognizing the wounds and the issues from my past that left me vulnerable to people who would not love me or treat me well, and unable to judge character well. (Good resources I found in this area were the Cloud/Townsend books and a book called Love Is A Choice by Hemfelt, Minirth, and Meier). God willing, I will never get into a relationship like that again. However, though it left significant damage, it was also the catalyst for significant healing. I'm grateful, although I wish it hadn't taken that, but sometimes I can be pretty dense
