Belated birthday wishes for you, Gud. I'm wishing that this will be a better year for y'all. I have no idea about whether not remembering your birthday is a bad sign. There were many good things in my relationship with my ex, but he wouldn't have remembered my birthday even if he'd had the date tatooed on him with a dull knife.
eta: If you know she remembered Gud, then all I can offer you is virtual hugs.
