Treese, In my opinion, your daughter's texting is only a small part of what is going on w/him. Your h is very self absorbed and very much into himself right now. What he's doing is called disconnection. There is a stage, whereby they do distance themselves from everyone including their children and pets. I suspect your h is at that stage.
Also, he's not able to deal with the fact that your father isn't well either. They don't do sickness of others well at all.
It's very tough on children when a parent is zooming around the universe. You've tried to tell her in the best way possible. You might want to advise her that he really does love her, but right now, he's dealing with his own personal issues and can only focus on one thing at a time.
Treese, there will come a time when he will begin to reconnect w/his children. The question will be just how much or how little they will want w/him when the time comes.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
