I've got to have this conversation soon and don't know how to handle it.
Background is that ds is 10, has been seeing his dad for a couple of years and does not like his step mother, who is (in his dad's words) jealous of his children and can be very blunt.
Last week she told ds he won't pass his 11 plus. (which is next week). She was also very hungover when he arrived and didn't get out of bed till he got there. He can't stand her and I don't want her to be anywhere near him as she is regularly a bit of a cow to him. His older children no longer visit (I am told because of her).
OTOH there is not really anywhere else they can go of a sunday morning in the winter.
How can I broach this? Sorry if I am repeating myself, I did ask on a thread last week but there were not many replies and I am wavering and fretting 
Thankyou
