maynard...if you really think it might be BPD check out the book "walking on eggshells". skim through it before you buy that way you can tell if it accurately fits your W. if it does, it's a pretty good read and worth buying.
I'm almost positive without a professional diagnosis that that is what my ex has. she would go from happy/pleasant to full rage in less than 60 seconds and then back again.
