Losing a best friend is undoubtedly more difficult than ending a romantic relationship; it's sudden, unexpected and discomforting.
We have recipes for the aftermath of ending a romantic relationship: put on a scandalous dress, down some drinks, and be with your best friend at all times. It makes things tolerable when you break up with your significant other and can have your best friend hold you but you're in total crisis when you lose your girl and at this time you need her more than ever. You almost call her and say, "I need to cry to you about losing you." Yeah, you end up sounding like a crazy ex.
There aren't many girls who are best friend material. For me to best-friend-someone-up, she needs to basically act like a boyfriend but without the physical stuff... besides cuddling and such, which is a must in a best friend!
When you lose your best friend you lose the one person who knows your darkest secrets, which most of the time are very similar to hers. The older we get, the higher the bar gets raised for a best friend! They're you're best friend for a reason, because they're the best.
When you lose your best friend you have nothing to do with all of the adorable pictures you have in your phone of the two of you and even of just her. These photos are so much cuter than any photos you'll take with a significant other because BFFs are just adorbs.
We expect guys to break our hearts. It sucks but it's true. We don't really go into a friendship assuming that they're gonna break our hearts or give up on us. It's pretty rare when a guy sticks around but a best friend is supposed to unquestionably always be around.
Losing a best friend feels more personal in a way. It feels like betrayal, like an attack on who you are. When you and your best friend break up you get the message "I don't like you anymore."
You can't say, "let's be friends" after the break-up. More often than not this doesn't usually work with a significant other anyway, but with a BFF break-up you don't even have the choice.
You lose the person who accepted your insane comments and looked at you like you were sane while agreeing to participate in whatever you had in mind.
Sure, you can get over a best friend break-up just like you can with a significant other, but it's a lot harder to want to do. You're saying goodbye to the person you adore—the person who always makes you laugh, who you share clothes with, a bed with, makeup, drinks, hugs, secrets, pictures... a special kind of relationship you can't have with just anyone.
