It was me, not her, who cut the tie. I said there was nothing we had in common any more and perhaps we should just go our separate ways.
I could have written your post LadyHonoria, similar situation as yours and the death of a parent being the catalyst for the estrangement. I was going to tell you that, in time, you carve out a new life for yourself and build up a whole new family for yourself via friends, but I can see that you've already done that very successfully. Personally, I don't hanker for my family to be back in my life (my life is very much easier and calmer without them in it) but I can sympathise and understand why others would. You sound as though you have a brillaint network of very good and supportive friends; a prize worth 1000x more than a resentful family. Do you have a good relationship with your daughter?
