rawpain, yes it does. the change back is really a visual indicator of where they are. someone asked me if I thought she was trying to be hurtful, said honestly no idea. i mean you expect them to change back once the D is complete, but I guess perhaps the keyword is "expect". they can do as they please really. for me i just addressed the content of the message for that reason.
i'm very sorry to hear of your sitch and can understand why you would be wanting her to change her name. for me it was disappointing, but seeing it did help me to detach further. her rush to D I don't understand, but it is her life, her choice...all I can do is determine how I let it effect me.
my best to you rawpain, as you say we just have to keep on going and be the best we can be.
