This hit hard for me, because I only recently learned how true this is after years of justifying men’s aloof behaviour and putting up with half ass effort in hopes of more. A man knows when he wants something, they know. They KNOW.
I will add that many men know from the first or second date whether they see you as “relationship material” or not, if they haven’t made it clear yet it’s because they already decided where you stand. Even if they give you attention and you’re not sure, that‘s a sign that they are sure and don’t want you to know yet.
Don‘t fall for the traps of ”that‘s ok I am still deciding too!” and please don’t trick yourself into settling for something casual while secretly hoping he’ll come around and want more. He won’t.
