If you're an Aries, your best friend might be just the one to make a perfect romantic soulmate, Amy Zerner, an astrologer and co-author of Astrology for Wellness, tells Bustle. This is especially true if your BFF is an Aquarius, she says. When these two signs get together, they form strong mutual admiration for each other. While this doesn't always mean that you have to fall in love in a romantic sense, the two of you are set up to be a really great match. "This pair makes for both good friends and romantic partnership," she says.

As a Gemini, you probably love going out all the time and enjoying the party life. This can sometimes cause a problem with partners who aren't so eager to spend their evenings at a bar or a concert. That's why falling in love with your best friend can be the perfect situation. If they're your go-to person for a fun night out, then they're already on board with this way to spend your time, which is a huge plus when it comes to romantic compatibility. "If [Geminis] can find a best friend to do this with that doesn’t impede on their freedom, then they can ideally form a relationship with this person," Yuhas says.

Partners can sometimes run into conflict when they don't have the same ideas about how to spend their time. Some folks, for example, have trouble making spur-of-the-moment decisions, and would rather stick to a routine than shake things up on the regular. As a Sagittarius, though, this probably isn't you at all. "Sagittarius is all about catching last-minute flights and enjoying adventures that life throws at them," Yuhas says. This means that the bestie who you always turn to for an impromptu vacay can turn out to be the one you fall for. The two of you can explore the world without worrying about leaving your partners waiting at home, because you'll be there together.

"Aquarius loves their independence and they need someone who understands that about them," Yuhas says. "The thought of losing their independence can be terrifying and they often prefer to remain unattached because of it." But this can be a lonely path if you really want a romantic partner to share your life with. The good news is that you might be looking for love in the wrong place. Do you have a friend who really understands your boundaries well? They might be exactly the person you end up falling for. "A partner who can give them their freedom within the commitment may be just the one to win them over," Yuhas says.

If you're one of the zodiac signs on this list and you have a best friend who's more compatible with you than you could ever imagine, don't immediately write them off as just a friend. Maybe there's something a little more there.
