Recently met my birth family. What to do now?

So this is my story of searching for my birth family. I hope I'm posting this in the right forum. :o In the summer of 2011 I initiated a search for my birth family through the adoption agency through which I was adopted. It began really slow at first due to my state's law requiring adoptees being required to have their adoptive parents sign a consent form in order to initiate a search for their biological family. Since my adoptive mother is deceased and I have little to no contact with my adoptive father, I thought I was SOL. In August, Missouri passed a bill that allows adult adoptees to receive identifying information regarding their biological family without the consent of their adoptive parents. Once that bill passed, things developed a little bit faster. Still slower than I would have liked, though. I first received some non-identifying information about my bio-mother regarding her height, approximate age, and some medical history. That just wasn't enough for me, though. After 29 years, I needed more information. So I wrote a letter to the family courts in September requesting more information and was told that they would have to get in contact with my biological parents to have them release their identifying information to me. After this letter was sent, I was notified that my bio-mother had passed away around 16 years prior. To be honest, I was kind of crushed. Though, had it been more recently, there's no telling how devastated I would have been. Because my bio-mom has passed, I would need the authorization of my bio-father to release the identifying information. Around the time the bill passed in August, I also received a birthday card from my biological moms sister since this was right around my birthday. Ever since my biological mother had passed, one of her sisters had been trying like hell to find me because she promised my bio-mom that she would find me. She had been sending birthday and Christmas cards to me every year, but I hadҒnt received any of them. I can understand why, so Im not upset about that. Fast forward to this past Wednesday, I received the letter from the family courts that contained the identifying information about my bio-mother and father. Since my bio-mother had passed away, they also included the name and number for her sister that had been looking for me. I sat on the information for a day thinking about what I would say when I finally called. The next night I called my bio-aunt and we talked for almost half an hour. Before we hung up, we made the decision to meet up the next day. We decided to meet in the lobby of the hospital where I was born. That is where we had last seen each other more than 29 years ago and it was the first place we saw each other since then. I met two of my bio-aunts there and we sat and talked for a while before they called two more of their sisters to meet us at a restaurant so we could all meet and have dinner together. So we all met up, had dinner, and talked all about our families, my life since being adopted, and about my bio-mother. It was a really, really great time. IҒm looking forward to meeting the rest of my bio-family soon. But how much should I reasonably expect to be a part of each others lives now that we have been reunited? I donҒt really expect to be a part of every family gathering, but I would like to be there for some, if not most. I just dont want to force myself into their family and make it an awkward situation. I have yet to contact the man who they say is my bio-father. IҒm not 100% convinced it is the right man and would like to have a paternity test done before we get too far into the relationship. Since begininng this process, I have kept this from most of my adoptive family except for my sister who was adopted from a different family. She has been supportive of me through this process and I am grateful for that. Now its time to tell the rest of my adoptive family. I asked my Grandma and two aunts, who are my adoptive motherҒs sisters, to meet with me tomorrow to discuss this. They have all been like a mother to me in some capacity since my adoptive mother passed away almost 12 years ago. I dont want them to feel like IҒm trying to replace or hurt them. Im sure theyҒll understand, but Im still a little nervous about the situation. That is really all I have for now. IҒll update this thread and answer any questions you may have when there is something to update about or questions to answer. /novel
