If a woman you know is always subtly flirting with you, she's trying to let you know she's into you. Look for clues in her body language. She'll smile and make eye contact a lot. She'll hold your gaze for a few seconds before looking away. She may give you a demure look, bat her eye lashes, turn her body towards you and lean in close when the two of you speak. She'll make any excuse to touch your arm, shoulder or leg, such as when she's laughing at your joke. You also want to look out for her stroking her neck, which is a way to subtly draw attention and subconsciously tease you a bit, according to dating expert and author Tracey Cox.

If she's giving you a lot of compliments, especially on your physical appearance, it's a good sign she's at least attracted to you. She might smile and tell you that she loves your curly hair or squeeze your biceps and act impressed. If she is connected to your social media page, she may comment on posted pictures by writing "you look hot." Compliments about your successes, such as a promotion at work, can indicate that she cares about you on more personal level.

A woman who has a crush on you is likely to pepper you with questions about everything from your job to your family to your food preferences, according to relationship expert Janice Hoffman. It's her way of getting to know you better and determining your potential as someone she'd like to seriously date. She'll also remember things you've said in previous conversations and follow-up with you. If you're uncomfortable with her grilling you, Hoffman suggests turning the tables and asking her a bunch of questions about herself, which she'll be eager to answer if she's interested in you.

Nothing has changed from your playground days. Guys and girls still tease those they like. She might make playful jokes about the hole in an old T-shirt you're wearing or tease you about being a player or a heart breaker. She might playfully push your shoulder or lightly punch your arm, which is just the adult version of the "I like you" shove from childhood. If she really likes you, none of her teasing will be hurtful or mean. It is simply a way to grow chemistry and a rapport with you.

A girl who likes you will always find a way to be around you. If you work in the same building, you might find that she conveniently seems to have the exact same lunch break as you and -- what a coincidence -- she's ordering sushi from your usual spot. If you offer a general hanging-out invitation to a group of friends, including the woman you suspect has a crush, you can bet she'll show up. If she asks you to "hang out" one-on-one, perhaps to check out the new downtown bar or to go hiking, she really is into you.
