5. He doesn’t make her laugh anymore
While it may sound trivial at first, the ability a man has to make his lady laugh is important to her because it makes her feel connected. While it may not have taken a genuine scientific study to convince most people that a woman laughing a lot at a guy’s jokes demonstrates that she is interested in him, a study like that was actually carried out and the results are not unexpected. A University of Kansas study showed that the more a woman laughs while talking to a guy, the more interested she is in him.
