My guess is that your H stays in constant contact with you because he depends on you. He loves you. He just doesn't know it. He cares about what you think, he wants advice from you, you are the stable one. That's part of love. The thing he has with the other woman is a different kind of love, and now because he has a child with her, he probably feels like there is no way out. Again, facing yourself in the mirror and making the hard choices and changes is extremely hard to do.
