SD has gotten to the point where she blatantly ignores me. I have been trying to handle this in a mature, calm manner. I’m working hard on not letting this upset &/or anger me.  

While home, she avoids me at all cost and doesn’t communicate with me other than occasionally say “bye” when leaving. I handle the day-to-day operation of the home, including medical appts., school correspondence, etc. for the children. She recently sent me a text message (even though we LIVE in the same house and she sees me daily), asking me to sign a form allowing her to drive/park at school.
