My sd use to split time between our house and bm, now sees us every weekend instead. We use to be so close. Now things have changed;I have heard her telling lies to her bm such as, I wouldnt let her charge her phone,instead of the truth, she dropped phone in water. I asked her why she laughs and says because she wont get into trouble. Her bm is very irrational and hotheaded so I limit direct contact. Sd is disrespectful to me calls me "weird" and just picks at everything I do. She is an adult with traumatic brain injury but does not act like this to everyone. I usually try to have my husband to redirect her but it is not always possible.
