oh dear, what an unfortunate situations, sorry
Firstly that is absolutley shocking behaviour in front of your ds (dear/darling son, we use that phrase for a certain level of anonymity and because it could take ages to write out names) and you should not place your son in that situation again.
Which means you need to take a break from you dh (dear husband) until he has calmed down and knows he can't behave like that anymore.
I know you are a foreigner, in the nicest possible way, and therefore don't have family here but do you have any friends you could stay with for a couple of days, just to give you and dh some space and hopefully get to a stage where the anger has died down a bit?
With regards to having to go back to your own country, if you want to then do it, it would be your dh's loss and if he carries on like this then frankly it's no loss to you.
You will, I'm sure get lots more practical and sound advice on here in the morning, but I live in Australia so it's breakfast time for me and I just wanted to let you know that you aren't being ignored
Hope this helps (HTH as we say on here)
