One reason why so many people in this world continue to stay in unhealthy relationships is because they are afraid of being alone. They would rather be with someone that mistreated them or caused them discomfort than to be by themselves. So instead of perhaps waiting for the right person to come along, they grab hold of the person that is available right now. They might overlook some defect of character to simply fulfill their need for company. This can create a monotonous life pattern for the individual involved.
