Most women, when they meet someone they like, decide to really give it a shot and see how it goes. They don’t date other people. They are making a strong effort to let a guy get to know them. For them, the momentum is constantly building from day one. Men, however, stay in the “deciding” phase for a bit longer. They can be spending a lot of time with a woman, which makes her think he has decided he likes her, when really, he is still feeling her out. He may not be as emotionally or mentally present as she thinks he is—he may not be giving it his all yet. This is often the case when two people have been dating for about a month, maybe two, and suddenly the man just ends it. He just made his decision at the end there. He didn’t go from being crazy about her to changing his mind. He just hadn’t made up his mind yet.
