I've been with my DP a couple of years and he has a DD who is 7. He moved in with me last summer and has his DD with us every other weekend.
The problem is his DD has some behaviour problems. She is very argumentative, sarcastic, strops if she doesn't get her way, wants to take over when she is here.
For example she will grab hold of the tv remote and want to choose what to watch and not let anyone else get a look in. My 2 DD who are 8 and 10 are more quiet and tolerant and will just let her take over but I am not comfortable with this. If we do some baking all together, she will always want it to be "my turn" and try's to take over doing everything and if we say that it is someone else's turn she will get annoyed and storm off in a strop. It's either her way or no way. She will try and take things that belong to my DD and she lies all the time. Even if me or my DP hear what she has said she will still swear blind she hasn't said it. She also doesn't listen to us. For example she had a pencil case out and was starting to drop the pencils onto the floor. My DP told her to not and she just kept saying no and continuing to do it.
My DP is very good with her and is good at disciplining her but she doesn't change. It's exhausting being around her and I don't enjoy it. I don't like her or her being in my home around my DDs.
The waiting list at school to perhaps get a diagnosis of something is long so and even though she has a family support worker nothing is changing. I think it is just who she is.
She is older than her years in the way she talks and does use sarcasm and is rude and my DDs often don't even pick up on this, especially the sarcasm.
I just don't know what to do or how to feel. I love my DP more than anything but the dread every time I have to be around his daughter is making me stressed and anxious and unhappy.
