OK, so he said he was going to go away, book a last minute flight or something and I asked him to let me know where he ended up and if he got there ok.
He checked our joint emails this morning and since then he hasn't. He hasn't contacted the kids (which I thought he would because ds1 was out doing something new and exciting all yesterday and ds2 had a very cool thing on this afternoon/evening). I texted him to tell him how ds2 got on. No reply. I texted him to ask him to get back to me if he was ok. No reply. His phones are switched off. I have a horrible feeling about this, what am I going to do?
