It's been five years since He's Just Not That Into You hit theaters and made people everywhere think twice about calling their summer fling for the twelfth time in a row.

In 2009, Ken Kwapis, New Line Cinemas, and a brilliant team of writers created the film version of He's Just Not That Into You, based on the book written by Liz Tuccillo and Greg Behrendt. The film, which chronicles the relationships of various ridiculously good-looking actors, opened the eyes of many individuals who might have been in denial about where they stand with their significant other.

Whether you want to admit it or not, you left this movie with a new perspective of what it means to date in the 21st century. And ladies and gentleman, there are just some things you should not do.

Let's be honest, the movie mentioned almost all of them, saving moviegoers everywhere from popping up randomly at bars hoping to run into their new crush.

In celebration of the film's five-year anniversary, here are 11 Reasons Why He's Just Not That Into You Keeps You from Being Absolutely Crazy.

1. Alex is the necessary friend you secretly hate, because he tells it like it is. His character could never be your friend in real life because you are a bit too sensitive. But hey, it's a movie! You could always walk away from the screen... But you won't. **evil laugh**

2. After watching the bathroom scene, you made a pact with yourself to never, EVER let yourself feel that lonely.**Sighs**

3. To no fault of our own, we realize we have to let go all of the dating rules we learned in pre-school. I guess our parents thought we'd forget when they told us a boy likes you if he's mean to you. Thanks, MOM.

4. Having hope is not a bad thing, because sometimes love does come from the most unexpected of places. **Sigghhhh**

5. Sometimes bad guys really are just bad guys. And then other times, they make friends with Scarlett Johansson. It's just all down hill from there, either way.

6. No reason to feel bad about missing someone's call. There are way too many ways to get in touch with people.  **Sorry! I missed your text because I was on Facebook chat, talking about the Instagram post I found on Twitter... Oh, and I don't even know what a voicemail box does.**

7. Listening to friends who aren't that great in their own relationships only leads to more friends-time, and I love my friends... But, no thank you. It's just unhealthy.

8. You learned not live by anyone else's rules. Your happiness is your happiness. Right, Jennifer Aniston? She knows everything. Just look at her hair.

9. If worse comes to worse, and you make a huge mistake... There's no way you are as crazy as this girl.

10. Remember that breakup that came from out of left field? The one that you are still confused about, years later? Everyone has those. You are NOT alone.

11. Through it all, no matter what happens... You will be okay. Even if you have to start over, the hardest part is behind you.
