gosh! you are all so very kind! 
queen you did not sound negative at all, you are right, part of wanting to sell and buy immediately is that properties in london are always on the rise,so many foreigners are buying atm,so if we can afford a 4 bedroom house now, we might not be able to in two years time.
sleep at the beginning,we though "oh,that will be easy we will pay for his place" but after having a talk with the school,they had some concerns,because he will attend an international school,its one of the best ones but does not fallow a british curriculum , if we can get him into a british one they might take an exception,but the only british curriculum school in the entire country has a really long waiting list,even dh company,and its a big name, cant help us in that matter, not to mention way costly to pay for his place ,where we are moving is really expensive.
linus if the dcs were younger we would have moved in a heartbeat!
funny thing is both dh and i lived in various countries,but we have reached a stage where enough is enough,we dont want to do it again.
i was skyping with my mum earlier,and she was saying:dear god! why are you making such a huge deal! you have been moving all your life. she then told me :right now,you should only be concerned about how puffy your eyes look from all the crying,and go and fix your hair it looks terrible! that made me 
,its her own wired way of telling me it will be ok!
thank you all for your lovely and kind advice, i feel kind a stupid and silly, i want to help him,but everything i say gets misunderstood.
will keep quiet for the next couple of days,and see what happens
