I hope D12 connects with her IC. It sounds like the first meeting could be called a success. I'm glad.
You don't update about D9 quite as much - I assume because she is not suffering the same anxiety as her sister. How is she doing?
I agree with you on your thoughts to not ask H for half the cost of the lawncare. You are having it done so you can enjoy it while you live there - so you choose to pay for it. That makes sense, and has the added benefit of being a "no-pressure" decision. Asking him for money would be tying him to the house when he clearly doesn't *really* wish to be right now unless on his own terms.
With your amicable/friendly co-parenting right now I think H is responding well to your independence. Keep this up! You've got it covered as a competent woman and mother.
I wonder about your last sentence of living in limbo. Do you still feel limbo? Or have you released enough of your H that you feel more that this is just your new normal, and that you can now handle uncertainty and change with courage?
I feel limbo is a stage when we are still hanging on to the outcome too much. Once we release our hold on the outcome and accept that "what will be will be" I feel it's less "limbo" and more just living life with all of its twists and turns.
That seems to me to be more where you are at. Accepting the changes as they come with grace.
