You know that girl in your crew who clashes with you? Whether it’s because of her rude ’tude or her constant negativity, you just don’t quite get along with her. And this could cause some awkwardness when you’re both hanging out in the same circle. So face it: She’s here to stay, and you have to make nice. Here’s how to keep the peace -- even with your worst frenemy.

Toss Her a Compliment
This is a tried-and-true tactic for shutting down frenemy friction. Rather than going out of your way to avoid, ignore or brush off a not-so-nice chica, be the first to shell out an “I like your outfit!” She won’t know how to respond, and you’ll leave her beyond baffled. It might even melt her iciness and have her seeing you in a different light.

Float Her an Invite
Throwing a birthday bash or hosting a sleepover? Instead of keeping your guest list exclusive to a favored few, extend an invitation to your frenemy too. There’s no better way to say, “Hey, let’s get to know each other better.” The gesture will take her by surprise, and having your whole group as a buffer should ease any awkwardness.

Have Her Back
Get on her good side by, er, taking her side. Stick up for her the next time the class clown targets your frenemy, or when an untrue rumor has been spread at her expense. Showing her a bit of loyalty when she feels heated or helpless is a surefire way to soften the friction between the two of you.

Make Her Laugh
Get chummy with your frenemy by having a good laugh with her. A case of the giggles can break even the tensest situation and banish any bad feelings. So show off your funny side! The minute you two are chuckling, the vibe should totally delete any bad feelings of the past.

Lift Her Spirits
Can you sense your frenemy is a little down and out? Did she get cut from the field hockey team or sprain her ankle? Take an oh-so thoughtful approach and use your creative juices to construct a “feel better” card. She should be wowed and softened by your support through tough times and start seeing you as (dare we say it?) a friend.

Yeah, boys can be baffling. That’s why this quiz is designed to help you figure out if you’re picking up on his signals. Hopefully, it’ll clear up some of the confusion about what’s going on in his head so you’re not scratching yours and going, “Huh!?!”

Nobody’s perfect. In fact, you’re fine exactly the way you are! But everybody has room for improvement -- it’s a never-ending journey. Take this quiz to find out if you’re giving it your all ... or not so much.

Being single on Valentine’s Day can make a girl a little green with envy when her coupled-up friends keep talking about how psyched they are for the big day. But we’ve got suggestions for awesome V-Day plans that are so crazy-fun that they might make your taken friends jealous of you. Heck, the attached girls might even ditch their BFs so they can get in on the excitement!

Organize a Single-girl Swap
No need to feel left out when all the couples exchange heart-shaped gifts. Get a bunch of your single friends to draw names out of a hat for a present swap. Set a $5 price limit, then pick out cool prezzies, like costume jewelry or an artsy thrift-store vase.

Hold a Candy-tasting Bash
The fun in getting a box of chocolates is sampling all the different flavors. So invite a few of your besties over to your house and tell each guest to bring along her favorite confections. Then eat up!

Go on a Double Friend-date
Ask one of your single guy friends to grab dinner with you on V-Day, and have your BFF do the same. You can have fun scoping out all the couples at the restaurant and guessing which ones will actually last, based on how much fun each pair seems to be having.

Make up New Makeup
Create totally new lip colors without spending a cent. Just put a dime-size amount of lip gloss on the back of your hand, dip your finger in your favorite shade of eye shadow, and mix it in with the gloss. Even funky combos, like purple eye shadow with orange-y gloss, look really cool -- we’ve tried it! Bonus: This one’s just as fun with friends as it is solo.

Dance the Night Away
Dance, dance parties -- where you go into a dimly lit room with tons of girls and dance your butt off to the hottest new music -- are really trendy these days. Host your own by making a playlist full of upbeat tunes (we heart tracks by Lady Gaga, Katy Perry and Pink). Then have the girls over to get your dance on.

Create Your Own Candy Hearts
Conversation heart candies are a must on Valentine’s Day. Messages like “Tweet Me” are cute and all, but we know you can come up with something way better. Pick up a pack of the candies and a food-decorating pen (available at baking supply stores), then write your own phrases on the blank side of each candy. Your ladies will love getting personalized messages instead of the played-out premade ones!

At some time or another, you’ll surely have to deal with the discomfort of “the friendship triangle.” Put three girls together and, well, it almost always spells triple t-r-o-u-b-l-e! Here, we take a brutally honest look at this friendship dynamic.

You’re the odd girl out
You’re the one being excluded? Bummer. It never feels good when you think you’re gonna have a good time with the girls and then find yourself tossed aside like a spare wheel. So ya know what? It’s this simple: Remove yourself from the situation. Call a parent to pick you up, go to another room, put on your ear buds -- whatever you’ve gotta do to ignore these meanies.

You’re not having fun, right? So why stick around and endure any more of their bad behavior? You could try to hang out with these two again another time, but if they continue to treat you like an outsider, it’s time to ice them out until they’re ready to play nice (if they ever are!).

You’re the instigator
OK, be honest: Are you the leader in this three-ring circus? Are you influencing one friend to oust the other? If so, stop that right now. Fact is you might think you’re in charge, but you’re actually completely out of control because you don’t even recognize what’s really going on -- which is that you are jealous.

Yep, we said it. You feel threatened, and so you’re turning your insecurities around on someone else. But you’d better rethink your actions. You see, the thing about friendship triangles is that they’re ever-shifting. It could all change tomorrow when it’s your turn to be the odd girl out (see above).

You’re stuck in the middle
So you’re good friends with both of these girls, but they’re just not hitting it off. First of all, do not let the instigator (above) influence you into ganging up on your other friend. It’s just wrong. You chose to be friends with both girls, so don’t be put in a position where you’re expected to pick sides.

Look, it is not your job to be the mediator -- so don’t even try. If these two refuse to get along, the advice here is similar to that we gave for the odd girl out: Walk away. Then hang out with Friend A and Friend B on separate days -- and refuse to get sucked into their drama!
