If they are mean because they are feeling guilty, then my h is feeling very guilty because he has gone into mean overdrive with his middle son. And to think at the time of the bomb that he said it was just between us, and that it would make no difference at all to his relationship with his chldren.
But what kind of strange person deliberately alienates his chldren when they reach out to him? Truly that alone is confirmation of MLC. Actually I suspect that seeing his chldren stirs up feelings that he doesn't want to acknowledge, so he pretends he wants a relationship with them, but every time they get a little closer he pushes them brutally away. This is beyond touch and go, this is touch and stab!
