Wow ... what a story you have there! And welcome to the forum. If you need to vent about these things, this is a lovely supportive place to do so.
You might find that it takes a wee while for people to respond to your post initially, as there is a lot to take in!
You should be very proud of yourself over how supportive you have been of your kids' relationship with their father. I get the impression that you are very aware of how important that relationship is and that if there is any way it is possible for you and their Dad to live in the same country then it's crucial for them going forwards.
Unfortunately with this kind of decision sometimes what is best for the children isn't the greatest for you, but you obviously love and cherish them enough to put their needs first.
Wishing you all the very best with some extremely difficult decisions!
You'll get lots of support here so I hope you can come back and keep talking about it.
