I am living with my boyfriend and his 16 year old daughter. I've started to notice the more comfortable she gets around me the more I see things that make me uncomfortable. She will sit on her dad's lap and she talks like she is 5 yrs old. Calls him "Dadddddyyyy". She will come in our room if she is left alone to long in another room and she will lay in bed beside him and pull his arm around her or she will cuddle up behind him and spoon him.
