I've written a good article on this, you can find it on my new website, if a girl seemed really into you and suddenly got flakey. Perhaps you showed some beta behaviour? Check it out here. Always open to constructive criticism, new ideas are welcome. Also feel free to e-mail me if you need more advice on the topic.

Edit: Can somebody tell me why my link isnt working? Just copy and paste the URL if it doesn't work
