Intelligence isn’t anywhere near as important to guys who are looking for a partner as other factors, as long as she has sufficient social skills and common sense.
That said, there is a minority group of men who look at intelligence in a potential partner as a major factor.
These are men with advanced college degrees.
These minority of men seek out women who are highly educated too.
It is not only one of the best hints that makes a guy notice you like him; it is possibly the best.
Although it feels intimidating at first, getting into the habit of making eye contact with a guy you like does an immense amount of good in your love life.
