Would u say men overestimate attention

Yes they do. I had a friend that was interested in a woman. He was overweight and not really a catch at the time. She was very attractive. She was nice with him and he thought she liked him. Myself and my roommate said she was just being nice. When he was finally rejected, he placed it all on her and none of it on himself. Luckily now he saw the error and no longer does that.
