I think the OP's main point was that when you date a woman in her 30s, there's a lot of pressure to get married and have babies ASAP. Because while it's certainly possible for a woman to become pregnant in their 30s, the chances pretty much go into a freefall during that decade. So even though as a man, you stand a higher chance with women in that age range, you'll always have this lingering doubt of whether she's with you because she wants you or if she's with you because she's running out of time. You're right though that there are plenty of other reasons a woman could be interested in you, but I think you might be underestimating just how loud that biological clock is ticking in a woman's brain when she hits 30.
