Every relationship has its ups and downs, and most couples who are together for any length of time find that they will argue at some point. Different couples have different styles of arguing. Some couples disagree intensely and quietly. Others talk things out in an annoyed but controlled pace. A few lean towards raised voices and emotional outbursts. Any of these ways of arguing aren't inherently unhealthy, but there are signs you are fighting too much with your significant other.
It can be hard to gauge your own relationship. You're inside the cocoon of something private you've created with another person, and even when you're both struggling, it can be hard to see clearly what is going on. Or, you might not want to see. It's difficult to admit that something so important to you isn't working well. Sometimes you have to take a step back and lay out the cold hard facts to yourself to really access your relationship status. Some people find that journaling helps illuminate patterns or problems, some turn to couple's therapy for an outside intervention. Whatever path you take, the first and most important step is to realize there is a problem. Read through these red flags and see if you relate a little too much for comfort.
