These things become much easier to deal with if you adjust your expectations. Sending a condolence card seems like a stupid thing to do - for a normal person! But for a WAS/WS, it’s completely normal.
She did wish me Happy Father's Day verbally, so I don't think it would have killed her to give me a card that said the same thing.
No card would have actually been preferable to the one I got.
Her parents and brother gave me actual, nice cards with cash and gift cards inside. And they are aware that she wants to divorce me. (I do not expect a gift from her, of course).
My niece (who talks to W a lot but is usually quiet around me) wrote "I love you so much" inside the card.
You can bet I will be keeping those cards.
If nothing else, any belief I might have had that I was the only one responsible for this situation evaporates with each of these actions.
