Let me try. I haven't read your whole biography on it but I'll take a stab.
When a guy falls for a girl, especially his first he goes all out. Sometimes over the top.
A girl on the other hand thinks about things. She judges. She wonders. She tests. Most importantly she feels things out. At first things can feel good. The guy can be charming. However a point comes when she wonders if she's with the right guy. So she tests some more and starts to think, maybe not. So she does one of several things. She tries to force a break up by doing stupid things to make him think badly of her out she waits for an opportunity to end things. Sometimes both. If neither present themselves easily the breakup talk happens.
Anything sound familiar?
