I an not a trans widow but I read this thread to post my solidarity with you wonderful ladies.
I really imagine that support is important so I personally think telling helpful, trust worthy friends is a good idea.
If any of my comments here are not helpful, please ignore.
I'be just been reflecting on my own head in terms of telling or not telling friends
I wonder if I could ask those who have been through this how relevant the ages of the children are when tellng friends?
I do have a few friends unconnected to my kids. Then a few friends who have children in my son's year 3 class. Most friends are connected to my child's year 8 class.
We have trans 'issues' in wider family and friends, not my husband, pretty much all females.
I've chosen who I talk to carefully, and not included the mums or dads whose year 3 or 8 kids have anything to do with my kids.
I don't want my children having to answer questions about this at school but if it was their choice to talk about it, then fine
My son is adopted and this is private info kept from most new friends (those who knew us when he came know, of course) so I am clear this info is private for his sake (because 7 year olds like to fit on!). I do tell people it is private since the day I heard a friend telling her friends in my earshot that my son is adopted.
However, when he told his best friends I said fine, his choice.
Yes, I know it is very different. But adoption can throw up questions and judgments.
I am not sure that there is a right way to deal with personal info, it is all down to the person or persons it affects.
But I think it is worth thinking how you tell and whether you expect people to keep this confidential or not, and be clear.
I can sort of try to imagine if this had happened to me when DD was pre school I might have told anyone. Now she is at secondary school, I would be careful with people who had a connection to Dd's school and especially parents of her friends.
If I did not have kids I'd probably tell close friends automatically.
But I also think, much as anyone is angry with their husband I'd let him tell who he wants and not feel the need to broadcast it.
Some will disagree!
This is not because I think there is any shame for wives at all, but because I think the husband should go at his pace and although I think it would be foolish to imagine he will dessist I think everyone knowing might accelerate things in a bad way.
I really hope you don't mind me saying that.
Trans widows may no longer care if the husband accelerates but for kids (if kids are involved) it might be better if he goes really slowly, so they adjust to the divorce and then are faced with the full reality, IMHO.
Those who are supportive about a person getting divorced might be the most supportive when they find out the real reasons. So I know people will avoid like the plague anyone trying to get you back together!
As I say, I really imagine that support is important so I personally think telling helpful, trust worthy friends is a good idea.
