Good post, Holly. I am glad you are there for her. I keep in touch with my email and I know that at time this is so hard for her. I admire her so much because regardless of the rough road this causes her, she does what she feels is the right road for her.
God will lead her to the right path...we just need to support her in the meantime.
Everything happens for a reason, maybe Dad needs to find that it isn't better out there, he needs to realize how good he had it here. Maybe he will find God and that is the most important thing when he finds Him he will know he is supposed to come home.
