"If CEA goes, then so will I"
No you won't. Here's why.
If it goes you have 2 options. Leave the services and keep the kids in the same school and pay it all yourself, which will mean a huge outgoing and lower disposable income on an equivalent job in civvy street. And if the stability is so important to you, you'd do exactly that now without the threat of CEA being taken away.
Or
Leave and put the kids in the local comp. The only thing that has changed is that you are now "seeking employment"
I see very few people that use the CEA for what it's there for and as many others have said, it's people who have been in one place for ages taking the advantage of CEA to avoid a state school.
Do the kids a favour. Show them what life's really like and send them to a comp
(I went and it never hurt me.......)
(Yes I have kids. Yes they will go to a Comp school when they are old enough )
