In human childhood development, a transitional object is something, usually a physical object, which takes the place of the mother-child bond. Common examples include dolls, teddy bears or blankets.
Gee, that puts into perspective my experience of having a security blanket when I was a toddler. Momster likes to bring this up from time to time that I carried it with me "everywhere," even to the point that it was in tattered rags. That blanket must have been my surrogate mother. I now seriously wonder if she was jealous of it and may have facilitated its "retirement." She almost certainly tried to shame me for relying on it (does to this day).
On the other hand, I don't recall my exuBPDgf ever carrying around ... wait a minute... I had forgotten about this up to this point... she DID have some trinkets from different people. I remember a small cabinet of gifts from previous boyfriends, and perhaps family members. Gosh, I somewhat half-remember having some conversation of why she didn't keep my gifts there...
Something I do remember for certain, I now consider this a "flea," but after she dumped me, I had some of her things in my possession (which,
, included a blanket) which I didn't return when I had the opportunity. I kept them around for some time until I finally "buried" them (think viking's funeral). Since my exuBPDgf, I hadn't had the need to keep any mementos with other exgfs; I've found my memories (and in some cases the ongoing rapport) quite sufficiently sentimental. But with my exuBPDgf, I remember feeling like those things (transitional objects?) were the only things that I had left as evidence of my relationship with her, since she had no longer provided any kind of validation that was consistent with my memory.
Thanks for the info Skip and Geroldmodel.
