1. He realized you are “not all that” now that he has seen other sides of you. Perhaps he did not like your personality or thought you were too strong, pushy, brash, or demanding. 2. He had a better option or believed it would become accessible, and he wanted to devote his attention to this new endeavor. 3. You or the relationship consumed too much of his time and attention. He understood it was time to put other things first. You slid down his priority list.

4. You were excessively touchy or needy. 5. You were jealous, distrustful, or questioned his relationships with others or his commitment to you. 6. You or he rushed the relationship, and he saw it was headed in the wrong path. 7. You liked or loved him too much. He realized he wasn’t as into you as you were into him, so he wanted to give you a message that he was done, hoping you’d break up with him first.

8. You had a horrible habit or vice that he discovered and could not live with. 9. He disliked your family and friends. Maybe it was something your mother, father, or best friends told him. He understood that liking you more would entail more encounters with your family and friends, which he hated. 10. You didn’t care enough about him.

He had fallen for you but became afraid when he learned you were not returning his feelings. He shut down and went away because he loathed the idea of being harmed. 11. He was no longer drawn to you. This might be because you changed your physical appearance or because he discovered a more appealing choice, making you appear less appealing to him. Or it was all about lust at first, and he only wanted one thing. Once you handed it to him, you were less appealing to him.
