Nancy, thank you for sharing your story.
I intensely dislike LW here on account of her attitude. It seems that indeed, she has not really dealt with this painful episode from her past and may be intentionally framing the daughter she gave up in the worst possible light in order to feel better and more justifed in her own mind about the decision to give her up. I have to say, though, I find her extreme marginizing and dismissal of this newfound daughter to be incredibly inhumane, seeing as LW was the one, not the daughter, to initiate contact.
Adoption is an emotional landmine, whether you're the birth parents, the adoptive parents or the child who was adopted. I have known some adoptees, and a good number of them were bitter toward BOTH of their mothers, despite having been raised in a loving family who chose them to be their child. From my perspective, this felt ungracious, to say the least--but then, since this isn't my story, I can't chime in and say how I think adoptees or the parents involved should be feeling or accepting their situations.
As a child who grew up in my own birth family, I note the supreme irony that, where adoptees usually want nothing so much as to meet their 'real' parents (who are presumably movie stars or exiled European royalty), I had my moments of adolescent frustration where I was sure that finding out I was adopted would be something of a comfort--because then I'd have an explanation for why I felt like an alien when trying to communicate with my parents, with whom I had a lot of the usual teen conflict. To this day, I don't feel like I either look or think anything like the woman who birthed me. The grass is always greeer-looking from the other side.
LW handled her delicate situation all wrong. In essence, she should not have reestablished contact with her firstborn daughter if she was not mature enough to accept the girl, and the fraught situation, for what it is. In general, I believe it's better for adoptees to leave things as they lie, and be happy with the loving adoptive parents they have. I can only imagine the knife in the heart of adoptive parents to be in essence made to feel, after years of sacrifice for the child they consider fully theirs, to not be considered 'real' parents; as for the birth mothers . . . their heartwrenching decisions were made years ago, and they still carry that pain, too. Meeting the child they didn't get to raise will not heal all the lost years, and as for the adoptee--finally meeting the woman, a stranger, who couldn't keep them is not a recipe for peace of mind, either. They need to work to find self-acceptance another way, because meeting a birth mother produces no guarantees, and most likely, as we see with this letter, just exacerbates old wounds.
I'm only looking from the outside, but such is my take. It hardly seems like a mother-child reunion could have gone worse than the one we have here.
