I wondered the same, but the hobbyist would more than likely never know unless it was a complete "accident" and she's sure who that "accident" happened with or she was very selective with whom she disregarded hats with, narrowing down the options. Other than that, you'd have to DNA test (way more invasive than the average provider screening process) a bunch of random guys who value their discretion/safety more than anything... Darn near impossible. Most of them will deactivate their accounts and move states before they allow the thought of co-parenting with someone they barely know. The wife wouldn't be too happy about that either.
Which leads to either two routes for our lovely preggo lady:
A) Hunt him down through hell or high water and get absolutely nothing.
Or B) Don't mention anything. Fix your crown and move on.
I'm currently 21 weeks pregnant (havent fully announced it yet) by a great, old friend of mine. I told him over dinner at this really nice country steakhouse. Of course, like most men, he saw his life flash before his eyes... but after 2 shots of tequila and a deep heart-to-heart moment, he could finally Express his excitement behind the initial shock. He figured he'd never get the chance to have kids and I was never able to carry any... so this is an unexpected miracle that we're making the best of. I expect the same of him that he does of me, be the best parent that you could possibly be and you are NEVER alone. If you need help, I'm here. If you're up at 3am and exhaustion sets in, I'll be right there ready to take over for you. If you're overwhelmed and confused, I will support you. This is a team effort whether we're together intimately or not. He hasn't missed one doctor's appointment and comes by every other day (as work permits) to deliver great prenatal massages and gifts
