I have been a step mother for 9 years and I thought that my relationship with my step daughter (who is now 15) was pretty good until I found a note in the laundry about how awful I am. Also, I have discovered that my step daughter is making plans to try to live with her "real" mother. "Real" mother is not able to really take care of step daughter but step daughter seems to think that her dad stole her away from her "real" mother. - which is not the case. Step daughter tries to manipulate her father.I am at wits end with trying to figure out what to do about step daughter manipulating and where I stand with her. I can't have children so she is all I will ever get to have. When someone comments on how good a mother I am to step daughter, she corrects them or ignores the ccomments. It hurts to know that the time and effort I have put into building a relationship with step daughter has been thrown out because I am not the one who gave physical birth to her. Any advice on how to handle this?
