You know, my husband is a good man: he was actually looking into getting one. We're still pretty young, however, and after some extensive conversations on children, I came to realize that while he could go either way, it is I who don't want kids. (Never have.)
So I honestly wonder if this is fair to him. If I fell off a cliff tomorrow and he was alone, then remarried in 3 years to another lady, she might want kids and if he loved her, he would agree. If he fell off a cliff, my mind would remain unchanged. For this reason, I question whether it is fair to ask him...
