It been a issue since she keeps talking about it. I think she is repulse by them because she feels they will restrict her freedom.
End it man
sorry to say that but thats the REALITY that topic is TOO IMPORTANT.

she just isn't made for you thats all
so end it respectfully because you and her have different views and goals on that and say how you truly feel bout her but not having kids is a DEAL BREAKER and wish her future endeavors
