The worst thing you can do for yourself, your partner, and your future kids would be to pressure your partner into having children when she’s not ready or doesn’t want to. Her path is her own, and it’s completely valid.
My advice is to have an honest conversation where you try to understand where she’s at on this and why, without trying to change it.
And then if you determine that she really doesn’t want kids, or may not ever, you might have to make a very hard choice to either accept that and let go of your dream of having kids, or to follow another path without her.
But own it as your choice, without resentment. She doesn’t owe you a child.
I met a guy who was ~ 45 or so. He had been with his (then ex-) partner for 15+ years. She had wanted kids, and he kept saying "next year", "not ready yet", etc. Finally, at the age of 43 she gave him an ultimatum to make up his mind, and he replied "nah... don't want kids". She dumped him right away.
I met her too a little bit later, and boy, the resentment was strong with her. I couldn't blame her.
With things like kids, please don't be wishy-washy; make up your mind and set specific goals, timelines, etc. Kids are an expensive investment of both money and time.
