If your ex knows where you are and wants to see his children surely he would have contacted you about having them for long weekends or school holidays.
If they are old enough and it means them flying, some airlines will take them unaccompanied. They sit them near the flight attendants where they can watch that they are OK. You don’t state whether he is in the same state or interstate.

It sounds like you are confused on what to do especially with such a change. Perhaps see a counsellor if you feel depressed as it could be hard to move on if you haven’t planned this change . Take care .

sad confused

Sounds like you’ve already made your choice, what’s the confusion for? You can’t go back, he’s moved on, maybe you should too

follow your heart , what is meant to be……

good and nice story

nice story

That is a difficult position you have – I hope it works out for you all in the end as must be very difficult on the kids

I hope this situation worked out for your children.

Make a non personal attempt to contact him like an email perhaps or a fb message explaining that you would like to give him the opportunity to see his children . hut dont be pushy and dont expect a response just do it to know you did something right

I think perhaps for your own sake (as well as for your children’s), you should speak with a professional who will be able to guide you through this journey. It sounds as though you are still in a great deal of emotional pain and I really feel for you. I hope that you are able to find a path to happiness soon.
