My best friend, “Jen,” and I are in our mid-30s; we met as college roommates and have been a huge part of each other’s lives since then. I’m divorced with two young children, and she’s never been married. Jen has always been very particular, but lately it’s gotten much worse. She’ll ask a waiter 20 questions before ordering a sandwich, and sometimes even asks to see a sample of the sandwich before deciding. It’s the same thing with home furnishings and other simple decisions. Unsurprisingly, Jen has never found a guy who could meet her exacting standards but is now obsessed with the idea of having a baby to “pass on her genetics.” I was surprised by this since she never shows any interest in children. She talks about passing on her love of travel and books and music, but when I mention the realities of motherhood, she waves her hand and says that’s only for the first few years—that she can put up with it to get to the “good stuff.” Before she brought up this baby idea, I was actually toying with the idea of telling her to talk to her doctor since I’m pretty sure she has some form of OCD. I don’t bring my children to her place anymore because she gets upset if they touch her carefully arranged magazines. I can’t think of anyone less suited to single motherhood. Should I have a frank talk to try dissuade her? She’s already looking into sperm banks.
