Absolutely Annie and Smileless.
I think it’s possible to imagine that you understand estrangement without having experienced estrangement, but actually it’s not, unless you are an extremely empathetic person. Some people are of course, but for most people, the pain is difficult to imagine. To be estranged from your child is worse than estrangement from a sister, and I find the estrangement from my sister painful enough. Estrangement appears to often happen after an adult child marries. Of course this doesn’t apply to me because it was my sister, but I think it possibly happens sometimes after marriage because the new partner cannot accept their spouse’s family and seeks to isolate them from their family. I’m speculating but think this maybe the cause. We had some of this with my daughter and her husband and again, it was painful, but they’re now getting divorced and so her husband was ultimately unsuccessful in his endeavours to isolate her from us.
I still think Charles and William need to make their own decisions about how to proceed. It’s not helpful to suggest that surely Charles could find time to see his son, or that parents should always forgive. It’s not us, it’s them, and they need to find their own way through this without advice from us.
