Single digit ... Firstly, there's a HUGE difference between 1, 4 and 9. Secondly, you make it sound as if a digit is as innocuous as an ice-cream cone when in fact there's a whole story and lessons to be drawn from each one. For instance, is that digit that we split hairs about an ONS? That tells a lot about that woman ... basically she's not wife material ... that is unless you're willing to deal with a woman with serious issues and you're willing to do paternity tests every time she gets pregnant.
Is that digit a failed relationship? Again, a lot of useful information ... who was the guy, why did it fail? Was it an extraordinary circumstance or part of a pattern and you'll be the next addition to it?
