I've had some more thoughts on this. I think the card was more for D than for GS.

That's what I'm telling her. I think/ hope he is letting her know that he hasn't forgotten his Birthday and as he's thinking about her just signed it Steve. That's what she calls him, she calls her biological father dad.

After all, he hasn't been Papa for this little boy and (in his mind) may, just may have thought it would be a bit of a cheek if he did. He knows I would have sorted a card and present out as I did with GD in April.

She is the last person he would intentionally hurt, he's closer to her than to his
biological sons.

I'm trying to look at the positive in this and think, like you.....at least he did send a card.
