It's a nightmare. Wake me up.

[koalada]

Dear divorce busters. As I have mentioned before, it is my son's birthday on Monday. We usually decorate the room together the evening before and wake him up with a song. Then we have a first piece of cake for breakfast. This might happen at 6:30 am. My W offered that I could come over to the house, join the decoration time and spend the night in the house. Although I appreciate the offer I am not sure what to do with it. Due to the fact that I would also see her on Tuesday and Wednesday (although I would not spend any time with her but with the kids),I don't know what would be the right approach.
The good thing would be that I would feel part of the family and the children would experience some kind of normality for a few hours. Any ideas on this? We did not have any disagreement for two weeks (due to my changes).
Otherwise I would have to miss the decoration time and would have to get up at 5 am to be there for the singing. (we are not living in the same town).
