Does he like you? And if he does, does he like you as a real person, a woman; or is it just sex? How can you tell? Is it what he says? Or what he does?
There’s no point in wasting time on a man who is only interested in sex – unless that’s all you want too. But most women want more than sex, they want a real relationship; but unless you can tell if a man likes you as a person you will find yourself wasting a lot of time on men who will never give you that.
So you need to learn to spot the signs that a man really likes you.
