Is he in sales, by chance?
I ask because the following are sales tactics:
- Limited time offer
- Only offered to "the best of the best"
I agree that you don't exactly sound head over heels. And you're also rather young to be boxed into deadlines such as these.
Also, biological clocks don't mean diddly. Adoption, egg freezing, these are both options for not having a kid ASAP.
I would also like to point out that when a lot of women in the American work force take time off to have kids, their careers tend to suffer. This doesn't mean you shouldn't have children; it's more that it's a lot harder to lose out on promotions if you aren't getting good support at home/aren't all in with your partner.
Not for nothin', but he doesn't sound like he loves you, either (sorry). This feels a helluva lot like a business proposition to me.
