He hasn’t asked you out but he flirts with you!
This is always tricky, because you can’t tell a guy that you aren’t interested in dating him when he hasn’t even asked you out. What do you say to a guy who hasn’t even made his intentions clear?
Many guys who think they’re smooth players fit like a glove in this category. They tease you and seduce you, and yet, never make their intentions clear. By doing this, the guy would entice you, rouse your curiosity, and make you think of him often, and that would make you fall for him even before you realize it.
When a guy doesn’t tell you he likes you and yet flirts with you, he may eventually embarrass you by flirting in front of your friends, or worse, in front of a guy you really like!
Many guys flirt with the girl they like in front of other guys. It’s their way of trying to mark their territory even if the territory doesn’t belong to them. Publicly and outrageously flirting with a girl in front of other potential boyfriend materials is their way of telling other guys to back off because he’s in a better standing to date you than anyone else.
