This was one of the issues that brought my last relationship to an end (being 39y now).

I used to downplay it and together with my partner tried to find a way.

Anyway, this sounds like a relationship issue. If your partner does not want kids it's possible that some kind of decision is needed (that's what our couples therapist said which turned out to be real good advice in my case).

If she can't have kids - there are other ways like adoption,...

If this is impacting you as much as it sounds - find a way to get yourself a child!
