I have a married M/F couple lying in bed. POV is from the woman. The sex is over and the pillow talk is about to go sideways (which suuuuuuucks in real life). They're going to argue obliquely about having kids. He wants them but she doesn't. It's an old argument (most of them are) with familiar streets and landmarks but neither of them--especially him--want to hit the ignition switch (kids) directly because they don't want to acknowledge that a deal-breaker is forming on the horizon. He's more into the discussion than she is. It's his dime, so to speak. She just wants him to drop it before it escalates. I guess what I'm looking for are things they might say while still dancing around the issue without going over-the-top with "We're not getting any younger" or "Whose going to take care of us when we're old?" Or some guidelines as to what they might be feeling. Regret and resentment are the obvious ones, but I'm trying to get a sense of how the conversation might go and what things the man might express that hint at the issue without coming at it directly. I should add that this is a bit of flashback, time-drift-y thing where the reader already knows that the female MC is in her 50s and childless, though not necessarily that she was married and divorced in her past. That has been intimated and signposted but not stated explicitly. Any comments are welcome (beyond opinions on the utility of flashbacks... I'm not a fan either but this is a quirky, non-linear narrative).
