Watch both girls for any acting out in any way. Make sure they are taking everything ok. If D10 still doesn't know why she is sad, and doesn't want to talk to you see if there is someone she will talk to. It seems to me that she is the one taking this the hardest so just make sure she isn't putting a strong front up and taking on too much. She is probably starting to have to help out more around the house and with D7, plus school, her birthday with her parents separate...it is a lot for a 10 year old to handle. Make sure they both have someone to talk to that they feel comfortable with whether it is you, W, a close friend, a close adult, anyone to share their feelings with.
Good job making sure W knew about a big even with D7. That will show W that you are going to do the best to be coparents as possible no matter what happens between the two of you. Plus it shows the girls that you will work with W for them.
