Here’s a good rule of thumb: Whenever a woman cancels a date and doesn’t offer an alternative time, she is rejecting you.
It doesn’t matter if the excuse she gives sounds plausible, or you have proof that she really can’t make the date due to other obligations. If she doesn’t offer a make-up date, she’s not interested enough to see you again. You *could* press the matter, but you’d be better off forgetting her and sticking with girls who demonstrate more enthusiasm to spend time with you.
In my experience, almost every girl who has cancelled a date for a presumably legitimate reason, has offered another time to meet if she already had it in her heart that she wanted to fuck me. Knowing this, it’s tactically savvy to refrain from counter-offering a make-up date until she has had a chance to make her counter offer. So when a girl cancels on you, give her space to offer another date and time; don’t rush to suggest an alternative meeting time. Like trial texting, this is a great way to gauge a woman’s emotional investment in you, and to consequently avoid dropping too much money and time on girls who are on the fence about their feelings for you.
