I'm glad you returned and posted an update. I'm also glad that you've set up a separate email address which you and your h can utilize when communicating about the children.
I'm sure the kids will enjoy spending Christmas Day with you. I do hope that your h will do something special for them on the day he has them.
As for the bizarre wording that he writes, it could all be part of his past w/his parents. The holidays do bring out some rather odd behavior for some and some of them do experience their own "Christmas Carol" story of the past and the present. So, I would just let him talk about things and if they sound off, just let them go. The ghost of Christmas Past sounds like he came just a wee bit early for him.
Keep the focus on you and your children. I'm sure you and the kids have been decorating and have fun doing so.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
