Life is untenable
I live with my partner, my 2 children and his 15 year old daughter. She came to live with is last year, having been in boarding school for the last 5 years. I moved my children to a different area do that she could live with us as her parents agreed that boarding was making her emotionally detached.
I can't lie....she's making life awful. She's rude to me, plays me against both parents, swears and is a complete self obsessed princess. She has ooenyl said she's not willing to try and make things work. She is doing her GCSEs this year so the year has to be about her. All she wants to do is eat, study and sleep and we can f off.....nice chikd!! She even told her father last year that she wanted him to move out of her home so that they can live together. She has major jelousy issues.
Her father will not condone the behaviour other than lip service to me as she has done a wonderful job on emotionally blackmailing him; saying he a and need her, set up life with me and my children.
Her mother plays a pivitol role in this. She was the one that put her daughter into boarding, even when my partner asked that she live with him (before we were together).....and it's not like she works....being a parent by proxy is more her style.
It's her mother that has drip fed comments about me to her daughter and even told her daughter that she knew living with is was going to be horrible. Her mother and I came to blows just before christmas and my stepdaughter Heard. I apologised to both and explained that I felt as though I was being bullied and needed to stick up for myself. Her mother and I are now talking again, but I am fully aware I have a knife in my back when I'm not around.
We have tried to mamagemthe situation at home, but my partner doesn't want to rock the boat further with his daughter. Rules?..... She doesn't have any and never has. A punishment is never followed through and my partner says a strong approach is not the right way.
My daughter especially is struggling with it all. She has huge anxiety and has even said she's worried she will turn out like her step sister. When she stays with her mother it's like the whole atmosphere in the house lifts.
I've tried being a friend, ignoring her, and alsoalso nonchalant. The child hates me and my children and the thought of another year of this is making me ill.
Any advice, sympathy, verbal "pull yourself together" gratefully received.
