Women in the dating market usually fall into two basic groups: those who like a specific man from the get-go, and those who don’t.
For women in the first group, you simply need to pick up on their buying signals and give them big doses of being yourself. Unless you have anti-seductive behaviors or major turn-offs, you should succeed fairly easily with this group. The main goal here is not to derail the train.
Women in the second group are much more challenging, because there is usually a boyfriend, a husband, another man they are “talking to”, or responsibilities lurking in the background. The only effective way to deal with these women is to become an attractor, not an aggressor, while showing absolutely no romantic interest until their interest level rises and they begin giving buying signals first. If you show romantic interest too soon, you’ll blow it. If your interest level gets too high too fast, they’ll sense it, and you’re dead meat.
The reality is that women in this second group should be approached with low expectations, because the success rate is much lower than with the first group. This is likely why, even though you asked for examples, few people can provide any. Most of these “long-game” situations happen unconsciously, meaning the man knows the woman but is unaware of her interest developing in the background, until something finally clicks for her.
