It sounds like he really does like this other woman, and since the two of you have only been on one date, there’s not really a relationship to break up. My advice is that although you like him, you should probably not refer to him as your boyfriend unless and until you’ve had a dozen or more dates together. This will help you gain some clarity on the relationship. He’s not really being a bad boyfriend. He’s just not interested in dating you. 😳 I know this is disappointing, but you’ll feel a lot better if you can think of him as someone you just had one date with, rather than a boyfriend who’s not treating you well. 😉
