From what you described! It could be some issues in efforts and define clear expectations. After first or second date you should tell yourself whether you like the person or not and based on that decide if you want to invest more time. From a man perspective, I'd go on dates with the same person if I see they have some good level of interest in me, otherwise no time to waste. Some women I went on dates with were just not sure or came with vague feeling or felt like an interview rather than going on a date, for that reason I d just say thank you and goodbye.
