Helping my children

I am supposed to be writing a story right now. I can't do it. I'm thinking too much about Isaac and Savannah. Specifically Isaac. He has always had a hard time with this divorce, and now, I think, two years of difficulty are coming home to roost. For the past month or so, Isaac has struggled mightily with his behavior, principally at school. He has yelled at teachers and students, tried to jump on other students, thrown things at people and flat-out refused to do what is asked of him. I have increased the frequency of my calls to him and Savannah since I was last there. He has not been the same since I visited him in March. He has been difficult at school and less so at home. My heart aches for him. I can't help but blame myself for this. It's easy to say that this problem with my son is a product of what Cherie did. It is, to a point. She took him and Savannah away from me. But I don't want to dwell on that. What's important is how I can help him. The easy thing to do would be to pack up and leave for Idaho. I'm trying to build a future for him and Savannah long-term. Cherie has even asked for me to move to Idaho. I feel like people are all tugging at my heart. Isaac and Savannah want me there. I want to go to school. Cherie even says she wants to quit school to concentrate on the kids. An honorable thing, to be sure. I wonder. Why aren't I doing the same thing? I want to go to school and get a solid foundation for the kids. I think she should move closer to where I live. There is family here, and she's closer to relatives of her own. She's further from Destiny, yes, but here, the kids have a built-in support system. I get the kids in June, but it's not enough. They need more. My heart aches for my children. I just want my children to be happy. They aren't, especially Isaac. Cherie is struggling mightily -- and she always has been. Why can't they just move here, Heavenly Father? There is so much here that's better for them. We don't have to be together. That chapter is closed. But my chapter with my kids remains open. I love them so much. I can't be having a good time and building a life for myself knowing the kids are suffering. I have to help them. I just don't know the right thing to do. I feel like I did a few months ago. Why couldn't we have figured this out years ago? What gives right now? I don't get it.
