Willow I found out that my ex husband's niece, my niece for 15 years, had died aged 27 years old. My ex mother in law asked, after 11 years, to see me and my son as she had some savings for him. On entering her flat she told me straight out that my niece had died. I had no idea. No one had said a thing to me. I instantly burst into tears. I was floored. I got told then not to contact my ex sister in law as my ex mil said that she was too upset to talk about it. Understandable, but we had been close when I was married to her brother. I thought about it constantly for ages.
Anyway, sometime last year, in a cafe, there was my ex sil with her new husband and her mother. She came over while I was in the queue, we hugged and I cried, told her I was sorry for her loss and that I had been told not to contact her when I wanted to. Much to my ex mil annoyance I went and sat with them for a while while I had my cup of tea. We did exchange numbers but nothing since and I don't think there will be now. But I said what I wanted to, gave her a cuddle and parted as friends, which I am glad of.
All I can say is that if you end up upset, then that is fine, it's natural, it is all part of the grief and shock of losing a beautiful young woman. Don't hold back neither, it will make her feel better to know that you are touched so much by it. It is a shock, look after yourself. X
