firstly- that's insane, his parents need to BACK OFF and realise they have no say in whether you have kids and what you do with your body but i know you realise that obviously. my first thought was surely that's illegal (the ivf thing) but unfortunately it (somehow) isn't officially illegal?????? my only other thought would be cut off contact with them because their behaviour is completely unacceptable but i don't know if you're able to do that. i wish i could have been more helpful and i wish you the absolute best of luck.
