ok so, you're basically having trouble with flaking...First you are going to have to start changing some things you do when you first meet girls. Then you're gonna have to change some things that you do when you try to set up dates.
First thing is:
DON'T TRY TO SET UP DATES THROUGH TEXT!
Man up and call her!
Look, I've set up dates with girls through text before and have gotten laid. It can happen, but for the most part, it is NOT the best idea. You have a much higher chance of getting a girl on a date over the phone than you do through text.
When I call girls I like to have a default story to go to right away. I'll usually set it up through txt first by saying something like "OMG the weirdest thing just happened. It kinda reminded me of u" or "Something totally reminded me of u, I'd explain but you'd hate me

" Then when they ask what it is, ill usually say its too much to text or I'll say "hold on, I'm kinda busy. I'll call you in a little bit." This way the girl is eager to pick up the phone when you call. Then I just simply tell a stupid little story that happened that day (even if it didn't really happen that day.) And by the way, the reason I give for why it reminded me of her is insignificant. Usually it's something like the girl in the story had the same name as her or the person in the story also was a soccer player just like the girl I'm on the phone with and sometimes I just don't tell the girl the reason it reminded me of her.
When ur on the phone with the girl, YOU NEED TO QUALIFY! This way, when you try to get her on a date, she understands why you want to go on a date with her and she doesn't think you're only trying to get in her pants.
Then, after talking on the phone for a little while, I try to set up the date. If you're talking to a girl and it seems pretty on, you can make setting up a date really simple. You can just simply say "Hey, what's your schedule like for the next few days?" Then you can say "let's hang out on xyz day at xyz time." It's simple, it's confident and it assumes the sale. Alot of times, you do not need to overcomplicate things.
If it's a little bit less on and you're a little bit less sure about how into you she is, you can say "I have a fun idea of something I wanna do and you seem like a really cool person to bring along." If you want, you can leave a little bit of intrigue and NOT tell her what your fun idea is. If you're talking to a girl who percieves herself as high-value or she's like a club-going girl who cares alot about social hierarchy (for the most part I doubt you will be dealing with these girls, but if you are...) then you might actually have to have a cool idea or something fun to bring her along to, because most likely she will have a lot of options of things to do on any given night.
Now, like I said earlier, you're gonna have to start changing some things that you are doing when you first meet girls. Just like you said, yeah, there probably ARE a lot of things that you are either doing or not doing when you initially meet girls that are making your girls flake. The first step to help stop flaking is to start qualifying more. Most students don't qualify or they qualify very little. I can't stress the importance of it enough. You qualify the girl when you first meet her so that when you contact her again (i.e. texting and calling her) she knows why you were interested in contacting HER specifically. Then you qualify the girl again when you're on the phone with her so that when you try to set up a date with her, she knows why you want to go on a date with HER. Then you qualify the girl while you're on the date so she knows why you want to sleep with her when you inevitably try to get in her pants.
Next step in stopping flaking is spending more time with these girl when you first meet them. If you have a good 18-25 minute conversation with a girl, the chances are much less likely that she will flake. Its easy for a girl to flake when she only had a 5 or even 10 minute convo with you when you first met her. By the way, how are you meeting these girls? Night time? Day time? and how long have you been spending talking to them when you meet them?
Another thing that will help cut down on flaking is to set up a date with the girl b4 you get her phone number. So, obviously you can't set up a date with a girl if you've only been talking to her for like 5 minutes, but if you guys have ben tlaking for like 20 minutes, thanyou can set up a date on the spot and the chances of her flaking go down even more.
But the MOST important thing is to QUALIFY!!!!!!
ya dig?
