Can you ask a child c? Definitely reassure them he will see them again and often and that he is not leaving their lives so much as moving his stuff to where he spends most of his time. It can be called a "trial sep" if you must.
I just know that my kids needed to hear what was going to remain the same in their lives such as if they'd stay in the school or neighborhood, and when they'd see him. My d, then 9, felt reassured when I told her we'd only move "a long time from now" and when we did, it would not be far away so she'd see her peeps...and I said, "I will make whatever choice I make that I think will make YOU happiest" and she remembered that comment a long time and felt a lot better. (A child C told me that one).
IF h isn't reliable about when he'll see them...cross that bridge when you get to it but be ready to do a little "covering" for him in the sense that you can't tell them it's b/c he doesn't care. You'll need to take steps to protect them later though so he can't keep disappointing them. Some will disagree but a book called "What About the Kids?" Says to reassure them that both parents love them (even if there is OW...)
Might try to get that book...good luck, ouch... j-
