A relationship can look calm, stable, even perfect from the outside. But more often than not, things aren’t as simple as they seem. You might believe you’re the ideal partner — always thoughtful, always trying to make your significant other feel loved and special.
Yet without realizing it, you could be showing certain deal-breaking behaviors that slowly push the two of you apart.
And the same goes for your partner. They might have their own red flags that haven’t become obvious yet. The key is to stay aware and not ignore warning signs.
Every relationship is different. But when one starts to crumble, the reasons behind it are often surprisingly similar. You may think your relationship is unlike any other — but chances are, you’re repeating the same mistakes many struggling couples make.
Here are some major relationship deal breakers to watch for — including the ones you might already be guilty of:
# CheatingThis may seem obvious — don’t be physically involved with someone else while in a committed relationship. But what about emotional cheating? What about that “best friend” who clearly has deeper feelings for your partner?
Cheating isn’t always black and white. Emotional intimacy with someone outside your relationship can be just as damaging. Because it’s subtle, it can quietly destroy trust before you even realize it. Protect your relationship — and your peace — by drawing clear boundaries.
# Making Decisions for Your PartnerDo you make plans on your partner’s behalf without checking in with them? If someone invites you both somewhere, do you automatically respond for them?
You might think it shows how well you know them. But over time, it can come across as controlling. Even if your intentions are good, repeatedly deciding for them can take away their sense of autonomy.
If this sounds familiar, it may be time to step back. Respecting your partner’s voice is crucial if you want the relationship to last.
# Superiority ComplexBelieving you’re “better” than your partner is a dangerous mindset. The moment you feel like they don’t deserve you — or that you’re settling — you’re already damaging the foundation of the relationship.
A healthy partnership requires equality and mutual respect. If you constantly compare, compete, or feel superior, resentment will grow on both sides. And without respect, love struggles to survive.
# Being Overly ClingyThere’s a big difference between showing affection and becoming emotionally dependent. If you rush into intense declarations of love or talk about marriage too early, it can overwhelm your partner.
Healthy relationships require space. Ironically, giving your partner breathing room often brings you closer. When someone feels suffocated, they instinctively pull away.
# Sharing Private Issues PubliclyA relationship is personal. Constantly complaining about your partner to friends and family — especially after every argument — can damage their image beyond repair.
While it’s natural to vent occasionally, repeatedly airing your issues makes others see your partner in a negative light. Even if you forgive them, your friends and family may not.
What happens between the two of you should largely stay between the two of you.
# Poor CommunicationDo you expect your partner to “just know” what’s wrong? Do you say “I’m fine” when you clearly aren’t?
Silent treatment and passive-aggressive behavior don’t solve problems — they create more. Your partner isn’t a mind reader. Honest, open communication may feel uncomfortable in the moment, but it prevents bigger issues later.
# Constant ConfrontationHealthy communication doesn’t mean turning every disagreement into a battle. If discussions quickly escalate into arguments, something needs to change.
Similarly, if you feel like everything you say triggers a fight, it might be worth reassessing whether the relationship is adding stress instead of joy. Love should improve your life, not exhaust you.
# Condescending or Negative BehaviorDo you disguise criticism as “jokes”? Do you and your partner keep score of each other’s mistakes?
Putting your partner down — even subtly — chips away at their self-esteem. A relationship should feel like a safe space, not a competition or battlefield. Ongoing negativity can deeply affect emotional well-being over time.
# Creating Unnecessary DramaSome people unknowingly create chaos because calm feels unfamiliar. Turning minor issues into major conflicts can drain both partners.
If you notice yourself escalating small problems or constantly stirring tension, pause and reflect. Stability isn’t boring — it’s healthy.
# Any Form of AbuseThis one is non-negotiable. Physical, emotional, verbal, or psychological abuse has no place in a relationship. Manipulation and toxicity are major deal breakers and should never be ignored.
Love is never an excuse for harmful behavior. If abuse is present, the relationship is not healthy. Seeking professional help is essential before pursuing any partnership.
