Hints that a girl likes me?

This is a while ago now so its not really important. ive recently started reading about the differences between men and women, what women really mean and have thought about similar experiences that ive read about. Question is: a girl i caught up with a year ago - we went shopping (she went shopping) and she was asking me what looks good or what i think of some clothes. I had to leave for work and after work i asked how the rest of her day was. She said she saw some hot guy after i left or something after. I think it means: "i like other guys and this is a hint that im not interested". Is that girls language for im not interested or do they do everything reversed? Im so confused
