First of all one thing that I had to learn for myself as a father is that we are responsible for our relationship with our children. You are not responsible for your Hs relationship with his girls. As you already know - he is walking out on your M. Why wouldn't he walk out on your children? Sorry to be harsh - but it is true.
If you need financial assistance for the children - then seek it. But don't concern yourself with your Hs relationship with his kids - this is his problem to solve - not yours!
I read somewhere that it takes about 3 weeks to rid yourself of a habit or change behaviors "permanently". So I recommend to you that you go dark on your H and not contact him for anything for 3 weeks. Use this time to work on Emily and get your thinking focused on you. Quit worrying about when/if he will call - expect nothing. If you need financial support, do what you need to do.
Horse back riding sounded fun right? Don't you want to do more of this kind of thing PLUS work on building yourself up? Then do it.
You can do it Emily. You have many rooting for you.
