My husband didn't sway and didn't believe in it or want to talk about it at all whatsoever. I felt lucky I was just able to get him to show up LOL. If he really thought I'd get pregnant at 41 he would not have gone along with it and only by the grace of God and my own sneakiness do I have a daughter today.
Re "feeling sneaky" I believe this: Men can and do pick up and start over again with younger women for no better reason than that they're horny and bored, and have whole new families and they do this ALL. THE. TIME. Even guys who you would never believe that they would, who have sworn their faithfulness and promised us the world, and these guys even leave their family in financial dire straits to do this and ruin their kids' lives. Whereas we ladies have a very limited and perishable commodity in our fertility and a brief period of time we can have kids. Thus I think that we gals may need to be more proactive in getting what we want in terms of our family size/composition and I do not find it to be any more "sneaky" than what tons of men do every single day and no one thinks anything of it.
