Yes, that is correct. Mom knows we are speaking to each other. I agree it is very strange behavior for her to provide the information. She provided that because she said (two years later) that she wants us to be a part of each other's lives and she also said that she wanted to send me a document to agree to a higher amount of child support, insurance and medical bills --- without going through the state that she currently resides in because she knew that they would "take more than I could afford", which she stated that she did not want to do that to me. I also find very strange that she would be so concerned about my financial welfare so much that she would not want to request through the state for child support.
Her behavior is very fishy to me, which is why I would like to know how to pursue this. It appears that she is trying to have the cake and eat it too (i.e. she has the child adopted, but would still like to continue to receive money -- more than she is receiving in the other state), but I am unsure of how to find out.
