Not everyone you like will like you back. She’s not interested. 😳 There could be a number of different reasons, like, she’s got a boyfriend, or has become more interested in someone else, or she decided that after three dates, she’s not into you — but the bottom line is that she’s being very clear with you, and I think that you’re not as much confused as you are disappointed. I get it. Find someone else to date who’s a better match. 🙂
