I have been the sole resident parent for 7 years. ExH lives overseas and only sees DC for holidays. Now DS (16) wants to live with ExH and I'm devastated. DS says he wants to catch up on time lost to see his father even though he is aware it was his DF choice to live in another continent. I know at 16 I can't stop him so am saying he can go, but inside I am broken. And am worried what it will do to his education, job prospects and also to his relationship with his DSis who wants nothing to do with their DF. I need help with how to cope with this. To avoid drip feeding both DC have ASD and other issues so are younger developmentally and need more care than their peers.
