When "what a woman does with her life" is to next you, it is relevant to you.
You're right when you say staying with a woman simply because you're afraid you'll have a drought if you next her is a bad idea. Incidentally, the fact we could end up with a long drought if we next her is why we typically have a damn good reason to next her. It takes a lot for a man to risk putting himself in a position where he could end up with a long drought.
On the other hand, it's been pointed out on this forum that a woman will next a man over something as trivial as not liking the way we look in one picture (even if the broad likes every other picture she's seen of us)
Since I'm on a 3 and a half year dry spell, perhaps I'm extra jaded. For me, long dry spells are a fact of life.
