Hard to know what really to do or which way to go. I know it was really tough for me to not contact and still struggle with it. My X seems to be unconcerned if I don't call as well. That is what she wanted anyway. But things have improved some recently as she is able to text me, called a few time also. I think people have different threshold levels and maybe your H's is somewhat higher than others.
I would just try to love on your kids. You are kind of communicating (non verbally) through them. It will get better. Hang in there.
