Pls help--confused and fearful

[Day by Day]

Need help responding to text from H:

Hello DBD, I want to spend time with the kids on Xmas eve to give them their gifts too. I could pick them up around 7pm and return them later that night... since you have them the entire 25th. If I don't hear from you I'll assume you are in agreement. Thx."

We did not make plans about where they will be. I made plans with them for the 24th evening already.
