Hi Kell - I said I would like to hear your story...so I tracked it down.
I am so very sorry that you found the mess that you did. I cannot even begin to imagine what you have been through. Nor do I blame you for moving on and leaving it alone.
But what I will say is that she obviously made the right decision in placing you for adoption. At least she had the where with all to think about what was best for you at the time.
Or maybe placing you for adoption ripped her entire world apart and unlike the admirable ladies I have seen on this site - she was unable to find her way out. Is this a possibilty ? Not that it would make a difference as obviously she is quite a selfish person now. She actually sounds a heckva lot like my stepmom...who had a dad in the military and once stationed in OKC, with two daughters younger than you. Interesting.
Did your adoptive parents know her prior to your birth ?
Sorry to intrude...I hope you dont mind.
