Hello Nannalouise and welcome to our new thread. It's lovely to see you here and to know that you've been strengthened simply be reading all that we share.
I can only imagine the myriad of emotions you must have gone through already. The hope before knowing the content of that first email, that perhaps this could be a desire for reconciliation.
A mixture of joyful and nervous anticipation when you were about to meet her again for the first time in 2.5 years and the joy and relief that it went so well.
It was IMO both right and courageous of you to ask her what horrible names you'd called her that was a concern about you having a relationship with your GD. I totally understand your anger that it appears that her being called pathetic, resulted in the estrangement and accusations of narcissism, abusers, liars and gas lighters.
It looks as if this new chapter in all your lives has got off to a good start but it's understandable and I think important that you are concerned about what the future may hold.
You need to think carefully and decide what boundaries you must have in place to do what you can to protect yourselves.
To even think that such a thing should be considered regarding your own child is something we'd never have imagined we would ever do until we were faced with their estrangement of us.
So rather than worry about what she may want from you, which is perfectly understandable, decide before she comes home, apart from of course your love for her and your GD, you are able/prepared to give.
I do wonder if EAC who wish to reconcile with the parents they've estranged, ever consider that it's not necessarily as simple as just walking back into their lives.
Having no experience I don't know, but I do wonder if it ever occurs to them that as much as their parents desire to simply welcome them with open arms, there is a fear that may never leave them, that they could be as you've said, "dropped again".
We love our children because they're our children and that love endures through estrangement, even if we are never reconciled. We want them to love us because we are their parents. We want them to want us in their and their children's lives first and foremost for the love we have for them, regardless of what we may or may not have have to offer in addition to that love.
