I don't understand why winter don't want a child can someone explain to me ?

I think it was implied in the manhwa that winter thinks violet is too weak (when he possessed violet’s body) to bear a child therefore he refused to have one, for violet’s sake.

I think because violet doesnt really want a child because she loves the ml and she just wants a child in substitution of divorcing

I think its not that he doesnt want but its because he cant.... Coz of bloodline i forgot what exactly it is but i remember hugo from Lucia when i read that part, that he cant have children until doing some requirements or something
