Amazing... and strange. Then again, like you said, he's let you know what works for him. For spouse's birthday I gave him a card. That was two weeks after he moved out. Nothing since.
While Christmas shopping it was just a tad strange not to look for things for him.. but that lasted only a nostalgic minute or two.
Hmmm... your ex-husband didn't want marinade.. did he think you wanted to 'grill' him... yuk yuk yuk. Humor!
