Bmom's parents warning against open adoption

As a birthmom I would want you to take my actions with you at face value and leave other people out of our relationship. There could be so many things at play in the parent daughter dynamic that you don't know about. Heck ask my own mother about me. She will tell you I am on crack and that I sold my child (all things she has said to other family members, mean while begging for pictures). Your relationship is with your birthmother not her parents. Her parents aren't the ones who are placing their child with you, she is. Perhaps she is all those things and you will later have to distance yourself from her but in the mean time doesn't she deserve the benefit of doubt until she does something wrong?
