I was a sulky 16 year old with an unsuitable bf.
I am not saying this is the case with you and dd, but I am going to tell you my side of things.
I wasn't allowed out in the week at all, I was allowed out on a Saturday night when I was in VI form but had to be in by 11. I did have a Saturday job, but I was employed by my father so didn't get any regular money - I got paid when my mum said it was OK.
I was forced to go to VI form. I hated it. I ended up in hospital and I'm sure it was down to stress.
My parents blamed my bf for me not telling them things, the truth was I'd not been telling them things for years.
I had no control over my life. I had no private life in my home. My mum didn't clean my room but felt free to open drawers, move things, walk in when I was getting dressed or when I was in the shower.
I was desperate to leave.
My mother now claims that VI form was her 'just giving me a chance' - well it was the VI form with the fewest ranges of subjects, lousy results and was a faith VI form - I'm an atheist.
When I did get a propper job, with prospects and day release training having A Levels was a disadvantage. It meant my employer had to pay fees for me to do a level 3 course.
My mother then took an unreasonable amount of board, before you criticise me. yes I had a home and it was heated but I had to buy my own food, toiletries, clothes, travel to work etc etc. Basically board got me a room and the used of the other rooms in the house, oh and I still wasn't allowed out much.
The 11pm curfew was a real sticking point and the only thing I ever dared argue about. I could get a bus at 11.15 - the last bus and other friends cought it. It would drop me accross the road from home at 11.30.
To get home for 11 I had to get the bus at 10.30, which involved me leaving on my own as most of my friends were getting the 11.15 bus. After crossing a town centre alone, catching the bus alone I then had a 10-15 min walk, again alone.
OK enough of my situation.
Due you think dd feels trapped? Being treated like a little girl? Not being allowed to grow up?
I am still having therapy about my feelings towards my mother and control.
16 is an age to start making descicsions, and mistakes. She is growing up, let her make a few grown up descisions. Try not to smother her.
What are her GCSE results likly to be? There are some businesses that do offer careers starting at 16. There are a lot of apprenticships around. Some careers even involve accomodation.
Keep the door open to her, we all have to make our own way in life at some stage.
