Scientists at University of Waterloo said people with low self-esteem have a higher likelihood of staying dissatisfied in the relationship because they do not voice their complaints to their partner, fearing rejection.
Study author Megan McCarthy said people with low self-esteem are more negative and complain a lot more, but only in social situation. In romantic relationships, however, people with low self-esteem shy away from addressing problems.
McCarthy added that people in romantic relationships need to pay attention for situations when their significant other was not engaging in open and honest conversations about the relationship. The reason is not they do not care; rather they are insecure and afraid of being hurt.
The research noted that people having a negative self-concept are frequently self-doubtful, and experience anxiety resulting from a potential rejection from their partner and damage to their relationship. The situation results in feelings of defensiveness, self-protection, and avoidance of confrontation.
The study concluded love partners should continue with the premise of forgive and forget attitude as constructive, especially when dealing with little annoyances, but it is a serious problem in a relationship that fails to address issues directly, which leads to destructive behavior.
