I agree RSF. Problem is, damage is being done. My own clock is ticking. My boys are going to be devastated when we move without daddy. As I immerse myself in my own life and managing the affects of all of this on my kids, I see the space for H in my life diminishing greatly. Granted, I never thought I would speak to him again after seeing the boys in tears when he left many months ago, so who knows what I am capable of forgiving? But, as you know, there is possibly a point of no (or highly problematic) return. My kids' hearts are in the middle here.
And that is perhaps a factor overlooked in your sitch too. At some point, we aren't just seeking closure and emotionally predictability for ourselves but for our children too...
