I made this mistake more times than I'll like to admit.you aren’t aggressive enough. Females will give you 1-2 times to hit it . After that they lose all interest in you. Yeah she’ll still hang out with you and talk to you. But she’s already looking for someone else.
speaking from experience. She’s friend zoned you . I remember when I had my opportunities and didn’t take advantage of it, you could always tell something was off afterwards.
Don’t believe that whole “ he just want sex, he’s a jerk because of it”. If she feeling you, she wants you to make a move ASAP.
Either in my naive era or my two job era
