. She wake up at 7 am, has her own room, no need to take care of kid during bedtime. I ask her not to hide in her room after dinner and should be staying in the living room to watch my kids. But, she keep hiding in her room and never come out after 9pm except asking by me. She even deny to come out when my son ask her to.

So, I don't agree that she must be in her room after 9pm. I talk to her about this issue this morning and see if she would change.
One week later, she told me she want to renew contract.
