Hi Perpetualsun,
The girl is simply testing your confidence level. It usually goes like this:
1) Great vibes, she is responding to your texts, she is replying to everything...
2) Suddenly she stops, or sends out some weird text or message, becomes bitchy and aloof...
3) She observes how the guy behaves, depending on his reactions she evaluates his confidence, perhaps even personality
The reason is simple, she usually feels some incogruance in his behavior thus she 'tests' the guy to find out how he really is. Examples:
Guy A:
is inexperienced, he is a Nice Guy, he has not much interactions with girls, but he doesn't pretend to be overly confident, he is rather shy. She will most likely NOT test him as she already knows how how he is, she knows that his behavior is congruent
Guy B:
He apears like a confident and sexy guy, yet there is some weaker reactions that she wouldn't expect from experienced guy. For example, she gives him good windows and he doesn't even register them. So she has to test him, she needs to test how confident he really is. She goes cold for example (as in Steps 1-3 above), or she may even pretend that she dumped him, or that she is with another guy. Now she observes his behavior. What is he going to do? If he is truly inexperienced, he will usualy freak out. He will start chasing her, start begging her to come back, start proving himself to her. He is done, he showed his cards, he failed the test, he revealed that he is not really confident... She will most likely reject him, unless she is really into him... This is IMO problem with many GC guys here, they know lots of stuff, they learn to pretend confidence, but they are not really experienced. Poor girl doesn't know what to do, so she has to test the guy over and over to find out what is going on. Guy like that is simply too confusing, he learns how to pretend to be confident or overconfident, yet at the same time he really isn't (e.g. misses windows, doesn't move relationship forward and so on)
Guy C:
He appears confident and sexy, yet there is some weaker reactions that she wouldn't expect from experienced guy. So she throws the test at him to find out. He, however, brushes it off, just keeps moving forward as if nothing happened. He keeps projecting confidence, he doesn't get confused by her Sh*t test(s). She's happy that he passed the test, and most likely will return to him. If he however keeps projecting not enough congruence, he will be tested again, this time perhaps even more harshly...
Guy D:
He appears like a confident and sexy guy, and he is confident and sexy in his behavior. He doesn't misses windows, he pushes the relationship forward, he utilizes his skills well. He doesn't pretend to be confident, he is, and he has experience with girls. She will most likely NOT test him at all, or just throws in some simple test for fun as he is quite congruent with his behavior...
So looking at the above examples, the WORST case scenarios is Guy B, but also Guy C. There is no congruence in their behavior, they are confusing, and she may have to test them even multiple times. Which is unfortunately confusing to the girl, and once she is confused she will withdraw, pull back. Guy B and even Guy C then usualy start chasing, which can be considered as failed test... In other words, Guy B usually screws himself by pretending to be somebody who he isn't, and Guy C may screw himself up if his game is not tight enough, or if he is not careful about making mistakes...
