Did he flirting me or just talking?

It depends on the guy and the situation itself. Some guys are just naturally friendly, and will talk to a girl with no ulterior motives, other than that they are being friendly, and they like the look of you and want to get to know you. Other guys will approach a girl with the hope of getting a date . It's usually possible to judge from the way that they act, what they talk about and their body language, such as making eye contact. Maybe they just think you're a really friendly looking girl. Either that or they find you attractive and want to get to know you, but that still doesn't mean they are flirting. Just enjoy the attention, and don't worry about it too much. It's not a negative thing.
