Yes, he knows what you want...do not continue to tell him how much you want things to work. The pressure it will put on him will make him more resolute in his decision.
Continue to be nice...you don't have to kiss his butt, but be cordial it will make it much easier on your children.
I'm telling you I know how much you wait for every opportunity to interact with him...I've been there, but you've got to get some strength. The next few times he calls let your kids answer the phone and don't ask to speak with him when they are done. If you have things you must talk to him about get it all over with so you won't have a reason to need to interact with him. The longer you go without talking to him the stronger you will get and the easier it will be. If you don't get to a place where you are confident on your own you will never attract him back to you.
