50% of their romantic fantasy is men making the first move, picking them from the herd, sweeping her of her feet validating her inner belief that she is special and you(a smart capable man) sees that as well
If they have to do the first move than you take that from them and therefore they will go the ends of earth to avoid making the first move and will find infinite ways to get you to make it until you do or they lose interest because you have proven to them that you are not smart or capable enough to pick on their hints as they thought initially and you don’t like them enough to capitalise on the opportunities they provide
Sometimes, you become intriguing to women on this site, and they like a lot of your posts in succession, hoping to signal to you that they have correctly intuited your nature, delighting in your worldview, knowing that you can take care of them help them escape from the tawdry, bitter world they are otherwise unfairly left in to fend for themselves.
But they should just DM! 😉
