Hello, would appreciate some advice please. My 17 year old stepdaughter lives with us and is now at an age where going to the pub has become a regular feature of life. She is pushing back on things like curfews (none are unreasonable, 11ish in the week and midnight at weekends in context of the pubs closing at 10), all of which is completely normal and part of growing up. We have no friends with teens and this is all quite new to us!
She has now decided that she is grown up, needs no boundaries and is going to do whatever she pleases tvm. Obviously this year has been very disruptive and difficult for us all, we have been cooped up together and she hasn't had as much social freedom as either she, or we, would have liked. With her education so disrupted she is doing what she needs to get through but spends most of her week lying in bed, contributes the bare minimum in the house and does the bare minimum in terms of work to get enough money to go to the pub with mates.
The issues are that, every time she goes out, she comes back drunk and defiant/argumentative and there's a row. If her father tries to challenge anything, her attitude is that she is nearly 18 and will do what she likes. My problem is that everything is take, and yes, 18 gives you more freedom which is great, but it also means taking more responsibility and being considerate of others. This is our home so is it unreasonable for us to set the boundaries for behaviour to live here?
I'm genuinely worried that she is going to turnout like her mother who is entirely self centred and irresponsible, and they have quite a few behaviours in common. On the whole I think she's a good kid and we genuinely don't give her much to rebel against, but from a happy household point of view, this screw you attitude isn't going to work for either of us. I have a stressful job and anxiety and so a peaceful, happy home is improtant for me, the thought of a couple of years of this tension and rowing is really worrying. We want her to have more freedom but the current pandemic is curtailng all of that and we find ourselves in a bit of a pressure cooker. Please share the benefits of your experience!
