This story just gets stupider and stupider…
“She said when they found out they were having twins, her partner who was carrying them, said she felt desperate and wished that one embryo would just go away.”
Here’s an idea. Have neither — frankly, for the mental protection of the poor kids, put them both into adoption/foster schemes (and yes, I know neither of those is perfect solutions either). Then you, and your partner, can go away anywhere you particularly feel like… but nowhere near kids, OK?
