I am sahm, single parent to ds and dd.
Dp left several years ago, is now minimal contact. Mutual choice, we would (and do) contact for important things.
He might even send dcs an Xmas card...
He pays nothing to or for dcs.
He is on ds birth certificate, not dd.
I am taking dcs to visit family in Europe in the summer holidays.
Now panicking (a little), do I need to tell him?
We will be gone for 10 days. Nowhere currently hostile.
He hasn't seen dcs since October last year.
