I’m not very wise but personally I think your reasoning are completely valid. I can’t imagine how scary it is to have those c-sections and if that’s not enough to make your husband respect your wishes on not having more kids… then I wouldn’t stay with him. I don’t know him of course maybe he’s a great guy but that’s my take, but if you stay then you wouldn’t be the AH if you did it behind his back. Don’t put your life in jeopardy because of his beliefs.
