DH is happy with our ivf child and does not want any more. He is 44 and we are only 5 years married and because of our age (me 43) he wants to say enough is enough and have time for ourselves later on. Another child would take us past 60yrs of age. However I want another child via ivf. Am I being selfish? (He already has two children from a previous relationship who he doesnt see very often)
