I relate to much of what you've said @Leigh925 too in post #16. Though I don't entirely understand abandonment- when you expect it it seems justified(?)
Just because someone has been trained to expect abandonment doesn't mean it is ever justified! No one deserves that. All humans are biologically wired to desire human connection....some of just happened to be born into families who couldn't or wouldn't or didn't reciprocate it.....but we didn't deserve it!
