W just picked S up. I stayed cool. I did thank her for letting him come over. She just said "mmmmmm" and made a face.

Probably because she told her friends that I don't want to see him, and her friend was within earshot.

I gave him a big hug as he was leaving. Then just politely waved as they drove off.

I'm getting better at detaching. It still hurts to see them both leaving though.
