I need to set a few things straight,
Yes my daughter has always been very disruptive. From the age of 18 months she was very difficult, me and her biological dad split up over her behaviour, as she was very defiant, and he didn't have any patience for her.
I met my current husband when she was 4, he helped me a lot, and the girls. Paid for me to pass my driving test, get my independence and has always tried hard to get along with both my daughters.
Unfortunately my eldest didn't take to him at all, as she favoured her dad even tho he left because he couldn't cope with her (she has never ever been told that!!)
She I was a very stressful teen, she was excluded from school, and has had some terrible boyfriends. But I've always been there for her, and despite her moving out at 18 I see her - speak to her - and do something with her nearly every single day.
Yes she isn't an easy person to get on with, she is quite abusive, and can be very nasty, but I love her and won't have anyone say anything bad about her! She's my daughter and he has said she can't come back. Yes it would probably cause upset, arguments and problems her coming back, but I won't see her struggle.
If he won't allow her back (we live in his mums house which is why I would have to leave) I will leave.
Whether she's hard work or not - she's my daughter and I don't particularly get on with his kids who are older, but I'd never see them struggle!!
