Im sorry for your sad feelings :,( I can relate. My BFs grandma triggers these kinds of feelings within me. I choose to not talk about him with her, and deflect her questions or whenever she brings him up. I love her so much, but she only ever wants to talk about him and the future or the past. I wish I had advice or words of wisdom, but all I can say is I relate, and I kinda fixed it in my life by letting her call go to voicemail sometimes, and other times just telling her I don't want to talk about him. hugs to you.
