Vent about in-law

I just need to vent. I am beyond enraged and don't know where to vent. My parter and i always had difficulty deciding wheter to go for children or not, it is a life altering decicion and ther are medical issues to take into account. A few years ago, i was toasting to my birthday and my father in law proclaimed that next year, it ll have to be three of us, dismissing our will and processes if decicion as wel as the medical issues. He even approached my partner and offered him a big sum of money if he'd have a kid. (no joke) I'm so dighusted by him thinking he can manipulate us into making a grandkid for him 🤮 Now on our anniversary he demanded: where are the grandkids staying (meaning: why aren't there any yet). I told him it is none of his business wheter we decide to have kids or not (of course he thought is was) and he continued asking why not and proclaimed that is the purpose of marriage (it is not for us, we married to celebrate our love and seal out commitment to each other more tightly) and that i should have disclosed my inability to bear children. (I'm not unable to have children that i know of) i told him we don't live in the middle ages and it is absolutely none of his business. I am so angry for his thinking he gets to have a say in this and treating me as if i am a breeding cow for making him a grandkid. 🤮 How would you handle this situation?
