Your story unfolds through the use of some nice dialogue. Going through a break-up is an incredibly hard thing to do and Nana understandably just wants to be left alone to mourn the loss. It's commendable that her mother approaches the situation with such empathy and care (this showed through her voice and actions in your story), and that her family gather around in support when they hear what has happened.
I would have liked to have seen more show than tell in your story. I think you could have used Nana's actions, expressions, body language, senses etc to show her emotional state and this would have created a bit more balance and interest. Take a look at this article from The Ink Well for some guidance in this area. show don't Tell.
Also try to avoid the happily ever after line, and the temptation to extend a complete story unnecessarily. Your last sentence introduces a brand new character and summarises the rest of Nana's life. Sometimes less is more.
Thank you for writing in the Ink Well. We look forward to your next contribution.
Thank you so much for the extra tip and correction, I will work on that. Lest I forget, a biggest thanks for the support
