A marriage researcher decides whether or not a relationship will eventually break down. According to him, the main reason relationships do not work is the lack of proper communication.

Criticism.
There is a big difference between responding lovingly to your loved ones and criticizing them. It can make them feel inferior and degraded. When you criticize your partner, it’s not just a creative critique; it’s pointing out the bad things about them. Instead, praise them and promote a positive image of them. If you have to bring something to their attention, do it as kindly and lovingly as possible.
Defensiveness.

Do not blame your partner every time something goes wrong. Acknowledge and admit that you are to blame. Always stop playing the victim. So be responsible for your actions. And admit that you are wrong, apologize and move on without getting caught by your partner.
Contempt.
Insults come in many forms. If your name insults, ridicules, or your partner, you are verbally abusing and insulting them. Even if you think you are just kidding, it can have a lasting effect on your partner, and you can cause them to become depressed. So stop it and start bathing them with love and affection.
Stonewalling.
This happens when the listener is completely inactive. And also, this is very disrespectful and hurts your partner’s feelings. Significantly, no matter how angry and upset you are, always communicate with love because no relationship can exist without proper communication.
