Dear Broseidon55,
Flakiness is not that simple to understand, as it can be, I believe, part of some game or, just genuine caused by some situation in the background that you cannot see.
If I take your examples, I think the first girl is gaming you in a very bad way. She is very sick. Maybe a bit premature to catalogue her as a freak but it's very likely. Does not mean you cant LTR a freak, as many of us have done that but it is something you have to be very strong about. LTR with a freak (I actually dislike this term) is tough, and that's maybe what she was trying to tell you by acting this way.
The second one is very different. She may have got back with BF and "trying to work things out" or many other things can be happening there in the background. Give her some space, this can mean a whole ovulation cycle (Cheers Hellhound I love your post) or any relevant thinking, reset period you and her may need. Taking it to breakfast if you are after an LTR is good however you know how women are in our countries, they like to game us for some reason. I would have gave it a safety period of time after this breakfast, for various reasons.
So yes, don't think they are all out to flake you, it's not all about you. Every case is different and just thinking "Oh she is flaking me" and throw her in the "Flaked" bag is not helping it at all.
Don't worry mate, life is not all about sarging and women, focus on your career, your real goal in life. Women are good to have but then again it is only secondary, you know what I mean.
Hope this helps. Good luck amigo.
