Hi. I don't know any other stepmums so would be grateful for any solidarity with what I'm feeling if poss?!
I've known my SD since she was 2. Her mum and my (now) DH split long before that. We've had a good relationship until recently and she's a cracking big sister to mine and DH's son.
SD is 11 now. We have 50/50 custody. We've all lived together since she was 5 and as far as I'm aware we're a family. We've had a great relationship so far. There's never been any issue in the past with me laying down (reasonable) ground rules, as in tidy your room, use your manners, don't tease your brother etc and I take the view this is my home as well as hers so I have a say on behaviour etc when she's here. I don't get a say in the big stuff, which is completely fine. She's not mine and I don't get to say what she can or can't do when it comes to schools, friends, phones etc.
But the past few months her attitude is HORRENDOUS. She lies, just little things but they're lies all the same. She's been in trouble over her phone and how often she's on it and the way she talks to people - me included. She's bought me to tears with her shitty responses before now. She behaves like she's 18 and it is really, really starting to do my head in. My DH is definitely the disciplinarian when it comes to her mum and him. He's stricter than she is, and she often defers to him for punishment (a kind of "see what dad has to say about this".)
Anyway. I'm rambling. Long story short we've had issues with Snapchat and phone stuff and her mum and dad now check the phone most evenings and monitor her usage. She has a tracker on it and a timer that shuts it off after a certain amount of time.
Looking through messages this eve between her and a boy at school, she's making out like she has a really horrible life with us. She sometimes goes to her nan's after school for an hour or so and has told him "she stays there loads when she's given up on her dad's family." She's told him she stayed there all last week but her dad "wouldn't let her stay any longer" and she had to come home today. It's all lies. She sounds like she comes from a proper broken home when the reality is she has a lovely home life with us and with her mum and we all get on really well.
I took her shopping over the weekend and spent £50 on an outfit for Christmas - my money. She's text friends the whole time she was there saying I'd made her go and I was "making" her wear a dress for Xmas day. What?! DH is furious and having it out with her.
I'm so pissed off with the attitude and lies but now also really hurt that she's saying shit that could potentially backfire on us.
Is she being a normal 11 year old and just acting billy big bollocks for a boy? I've already decided to disengage and not be so involved any more but any more advice gratefully received.
Sorry for the essay!
