5. She’s Flirtatious

Flirting is of course the universal sign of letting someone know that you like them. Other than verbal cues, you should look for signs like if she’s smiling/giggling more often, giving you subtle touches, playing with her hair, licking her lips, etc. These are signs that she likes you. Of course, a random girl you meet at the bar might be flirting with you to get a drink or two out of you, but that only happens sometimes.
