Why do you keep saying "if we were together, then x."? It seems to keep you stuck in a place that you're not. Why not open up to how things are now and think about how to make them the best they can be, given the current conditions? What could that shift in thinking do for you?
Also, when you say he can't/wont love you the way you want and need to be loved... You're not really being accepting of the person he actually could be at his best. Why not worry whether *you* could love *him* as he wants/needs? Isn't that equally valid? Or why not stop thinking you understand him so well and try to see him with new eyes? You seem hung up on the past. I don't see how an R could be successful if you can't find it in yourself to exercise a little grace.
Don't mean this to be a 2x4, though I see it might be read that way. But you've been stuck for a while. Wouldn't you be happier if you moved out of this space?
WRT to your daughter's having siblings or not... It's a recurring joke in our family that my D would have been perfectly happy to be an only child her whole life. you may miss additional children (assuming your future doesn't hold any, which is by no means clear), but that doesn't mean your D will feel cheated of her birthright.
I want to see strong, happy Claire back again. Where did that kicka$$ lady go?
