I agree with your hub in that you've sent a few emails and did indeed get a response to the Myspace contact. Let her contact you when she's ready.
From what you've written the issues with bgrandmom could still be there. Playing what ifs and projecting without really knowing what exactly the truth is...bmom may have spoken to her mom and might be going over how to proceed, she could be dealing with her mom or dealing with how to tell her mom about this now. If her folks were controlling 2 years ago they may still be regardless of her age and current status with family and child. Or really simply she could be busy with her family while trying to figure out how to proceed with your invitation to continue visits again. If it was emotional for you it was probably the same for her, so there must be things for her to work out..just like you all worked them out in order to get to this point now. Give her some time to process. Send the pictures to the agency like you've been doing with a note saying what you said here...that you wanted to send directly to her and will do that when addresses are exchanged but for now you wanted for her to have them as soon as possible.
I think that's how I'd handle. Wishing the best for you all
