I've been in my step-daughter's life for the last 7 years - part time (half the week) for the first 4 years, and she has lived with us full time for the last 3 years (with very little contact with her Mum).
She's 13 now and proving to be very difficult - especially towards me, so much so that I wonder whether it'll be better for us all if I tap out and stop trying to parent her. My husband has always given me full autonomy over parenting her and I've done what I can to try and treat her the same as I do for our joint child.
By taking a step back from parenting I hope that it'll allow my husband to be a better father - he can make decisions in an instant and react to the situation in front of him, without having to give my position any thought. It could make our relationship better, since the number 1 cause of conflict between husband and I are issues with step-daughter. Hopefully then, in time, the tension between step-daughter and I will also dissipate because she'd have no cause to resent me.
However, even if I step back there will still be issues that I need to address due to the natural balance of an adult and child living under the same roof, and I expect she'll still reject my authority - potentially even more. Additionally, I don't want her to feel 'left out' of her family which I guess could happen if only her father is parenting her, but we both parent her sister. I also worry that having her Dad all to herself could be everything she has ever wished for, and that maybe this could actually lead to a bigger split in the family entirely, of step daughter and Dad vs me and little sister.
What I do know for certain is her attitude and behaviour are making it more and more difficult for me to remind myself that she's just a child. When she was younger it was much easier to not take to heart her behaviour but it feels now that she knows what she's doing, and why she's doing it, but does it anyway.
I would love your opinions - shall I step back, since doing the same thing for the last 7 years hasn't made any difference to her feelings towards me? Or shall I double down, continue as we have been and hope that she appreciates the consistency one day?
