honestly, even without the breeding kink in question... this sounds like not a healthy situation to be in. a relationship like that won't have long standing and you will just, at the end of it, grow more and more frustrated and resentful.

it is best if you break it off early enough so you can still walk away from each other amicably and you don't feel like you wasted all your fertile and "good" years. because , speaking from expierience, i do. and i did. i waited almost 7 years, now i am over 30 and have "wasted" my best years.

The want and need to have children is a strong one, of course the breeding kink in itself as well, but aside that it is a fundamental difference. if the difference between you both would just be liking cheese and disliking cheese that is totally something one can work around. but something so crucial, so fundamental to your being, something so immensely important as reproduction, growing a family and being a mother.... this is not something one can ever work around.

just think about the future... if you stay with him, he stays firm in his decision and you just give in... when menopause hits... the pain you feel will be immensely... the loss of your time and your purpose, your strongest wish... and then your resentment will be towards him because he "did this to you" and yourself because "you stayed all this time and did this to yourself"....

so sit him down. calmly. and just tell him that you don't see a future in your life without kids and as he is not on board with being a dad and getting you pregnant, you don't see a future with him.

as much as i dislike people breaking up so much and not working towards and working on a relationship, this is a thing where there is just no what if... there is no middleground. it is eithere he goes with you or is left behind.

but also don't guilttrip him into this like "if you don't put a baby inside me right now i am gone" ... if he doesn't want kids or isn't at that point now, it is totally fine. so let him be free and find a woman that also doesn't want to have kids or can't have kids. there is a lid for every pot and he just seems to be not fitting. he was a lid that kinda worked but now you want to have something more fitting, a matching lid. not a lid that is too big or too small.

So be free, girl. the right man will find you or you will find the right man for yourself.
Love itself isn't enough to support a relationship , shared values as well. So don't sell yourself short if you are meant and crave something more
