1. A person with angry and aggressive nature
Anger can be a part of every human being's nature, but if a person becomes excessively angry and aggressive then it can be difficult to live with him. Such people not only get angry over small things, but can also show aggressive behavior at times. Such situations not only increase tension, but can also create an atmosphere of insecurity and fear in relationships, because such a person can also commit violence.
2. Excessive control over nature
A little controlling nature is not bad to maintain the relationship or to save it from difficulties, because it comes under the category of care, but if your life partner wants to have excessive control over every small and big decision and harasses you for this. If so, it is a sign that there may be a lack of freedom in your relationship. Such people often believe that their point of view is right and ignore the feelings and wishes of others. This may cause mental and emotional stress in future. Therefore, if you see such nature before marriage, then keep distance from him.
3. A person with negative thinking
Be it married life or career, no person can move ahead with negative thinking. Positive thinking is necessary for success. If a person with negative thinking becomes your life partner then life can become hell.
4. Cheater
The foundation of any relationship is trust. If your partner is not trustworthy or is a cheater, it can weaken the relationship. Such a person may often lie or run away from his responsibilities which may prove dangerous for your future.
