Goodfight, this is just my experience but I have intervened where my kids are concerned. My H wasn't able to be the Dad he should have been for a long time but I knew underneath it all he really loved them and I knew both my kids were really hurting. I would text my H something like, " D seems to be a little down lately and I think she's really missing you. Perhaps you could give her a call. Up to you but think it would help her." I wouldn't mention it again after that. My H has also complained that he has to chase the kids cos they don't call him. He has complained to me about that. I explain it to him that the kids want him to prove his love by chasing them for a bit. Good luck!
