The 1 Dealbreaker in a Relationship Based on Your Zodiac Sign

"An Aries is bold, warrior-like, and extremely proud," astrologer Valerie Mesa told POPSUGAR. Rejection is equivalent to their worst nightmare, and they can sometimes be petty about it, too, which doesn't do much for the relationship.

If you're dating a Taurus, don't think about being unfaithful. "Taurus is probably one of, if not the most loyal in the zodiac," said Mesa. "This earth sign is dependable and incredibly patient with their partners; hence cheating is unforgivable in their eyes."

A little white lie and Gemini will see right through you. "If they actually put their guard down to trust someone that ends up lying to them anyways, there's no turning back," Mesa explained. Honesty will allow Gemini to be vulnerable with you and further the relationship, rather than detach and take steps backwards.

Cancer is incredibly emotional, not to mention guarded, so imagine what happens when someone breaks their trust. "This water sign has an amazing memory and an emotional time clock that takes them to that very moment," said Mesa. In other words, it's over for good.

Leo is extremely prideful, so you don't want to bruise their ego, or else they may never let you in again. "So much so, if someone subtly tries to bring them down or hurt their feelings, they're going to be incredibly aggravated and may not forgive for a second chance," warned Mesa.

Be careful with Virgo's precious minutes, and if you're given them, spend them wisely. Don't make them feel as though their time isn't worthwhile. "Virgo is efficient, resourceful, and incredibly polite," continued Mesa. "However, rest assured, their refined persona goes down the drain the moment they realize they've been wasting time."

If Libra is upset, don't brush away her feelings. "Libra is a walking mirror. In fact, if they simply feel that their partner, or perhaps colleague, is lacking empathy, that's where the relationship ends," she said. Libra needs to be understood or else they don't get that validation and may no longer wish to strengthen the relationship.

"Scorpio is all or nothing, and once they've put their guard down and risked sharing their undying love with someone who ends up betraying them, there's no turning back from there," Mesa explained. If you start a relationship with a Scorpio, you'll want to remain loyal and communicative. Also, revenge maybe be likely, she adds. Uh-oh.

Sagittarius is everyone's friend, not to mention incredibly street smart, so they can often help you in a few situations. However, if this fire sign trusts you and they come to find out that you've been using them for whatever reason, they will disappear from your life for good, explained Mesa.

Be careful with humor around Cap, especially if they're the victim of the joke. "Capricorn is serious, righteous, and no bullsh*t," Mesa revealed. "If someone even dares to humiliate them or make a fool of them in the workplace, you bet your life it's over." Oh, and revenge may be present here, too, except there aren't as many emotions involved as a Scorpio.

Aquarius knows how to separate emotions and harden a bit, where they can write someone off when necessary. If you ignore an Aquarius, where they don't feel like you're in the relationship with them, they're done with you. "If they actually take time out of their day to acknowledge your presence, but you somehow disregard them entirely, that's where it ends," said Mesa.

Pisces is tricky, but everything and anything could possibly be unforgivable, explained Mesa: "You never really know what you're going to get with this water sign, as it has traits of each sign, which is a symbol of universal oneness. Your best bet is to pray you get the calm before the storm."
