No, doesn't depend on the person, my ex, cancelled on our third date, for a legimate reason. I was really into her, but if she cancelled that third date one or two more times, that's it I'm done. It shows a clear lack of respect for you.
Honestly, I don't take things like that so personally. I'll usually let someone know if they've wasted my time though. Of course when I say "it depends" one mistake I think people make is trying to plan dates several days in advance. That works for *some* people, but it also leaves room for people to become anxious about it. Dating someone new is high risk behavior, it really is, so it pays to be cautious and flakey. It's safer. Hot chicks are, in my opinion, notoriously flakey, in fact that may be a 'people in general' thing. People like a challenge after all.
I don't buy this, he or she could just like the attention and an ace in the hole if the person they really want doesn't work out. I'm not going to be anyone's plan B or consolation prize.
I don't buy that anyone thinks things through this much. Most people I want nothing to do with I just ignore completely. At the bottom of my iPhone text window there is just a lovely collection of people I simply never respond to. Like a text graveyard. Although this is where SuperMike and I basically part ways. I believe any girl that is openly very friendly to a guy probably considers sleeping with him
but attraction alone doesn't necessarily drive her to do it. When a girl tells you "no" really you should be making sure that "no" is final. One mistake people make time and again is they assume that they're the "loser" in this massive sea of "winners". Most relationship anxiety, nervousness, flakiness are common not uncommon. The girl who asked me out wanted to way back in October, and she's very attractive, and I know of quite a few people who wanted to get in her pants. The girl last Thursday, about the same stretch of time. The former takes medication for some pretty severe ADD, it makes her very challenging and very flakey, and very hard to read (she can be very emotional, then very stoic). That's her particular circumstance. For me though, this isn't a race. Of course I don't go about it quite like Obin Gam.
I referred to my "rule" as a pouting type of thing. It's more just not letting myself get strung along. I've had a few people cancel dates on me because they got sick, I knew where my friends where going to be that night, so just went there instead. I didn't sulk or anything. However, if someone continues to just make plans and break them, why keep trying to see them, they clearly don't want to see you.
I would make sure of the latter there before you make snap judgements. If they mean nothing to you, walk away. If you think they're worth it though you should always ask "why are you avoiding me?", "why do you keep cancelling our plans" or "I'm frustrated you cancelled on me".
