I'll keep you and your kids (and him) in my prayers.
I had forgotten he has no contact with you and the kids. By all means, they should hear it from you rather than from someone else. Or if they did,they maight be afraid of telling you because they know how badly it would hurt you. JMO
You will be able to comfort and support each other.
I am so sorry this has happened...all of it.
