Hey, I woke them up by phone this morning and took the girl. My ex called me few minutes later and asked me why I was unfriendly and didn't come in the house. I answered that everything was fine. She called me 2 more times during the day. When I took the kid back the environment was friendly. I stayed at their place for few minutes and then went back home.
I stopped calling her with her pet name because she also stopped doing it.
