There are a lot of posts in the seduction sub (also dating advice and askseddit sub) that are basically mindreading requests.

Why didn't she text back? Why did she flake? Why doesn't she initiate? We had a great date but now she doesn't respond etc.

And they all have the same answer: We don't know.

It could be external factors that are outside of your control, sure (ex came back, busy with school etc.). But more often than not she is just not that into you (yet).

Look at yourself. Try to improve your seduction/social skills. Stop trying to think for that girl that is flaky. There will be other girls who are the same or even better that will be into you.

Have some self respect. She simply doens't care about you enough to make an effort and you are posting online about it. Stop making excuses for her. She has a responsibility to make herself desirable. Being flaky isn't one of them.

Also if you post these questions understand that we weren't there. Why she isn't into you can have many different reasons. We only know what you mention in your post.

And even if you did everything right according to the seduction experts, some girls just won't like you because of a random reason.

You can only have a higher succes rate. You can never get every girl you want.
