When the people involved in the relationship realize that they cannot survive in it on their own, then the relationship becomes a survival relationship. The choice of partner is out of emotions and there is no match in personalities of the two. It involves both a physical and emotional relationship and the fulfilling of the basic requirements of a married life. These people are unlikely to share common interests and qualities because of which there is not much that holds together this relationship. Each person tries to provide the other person which the things he or she does not have which makes the relationship a desperate, clinging one. Sometimes the relation can also become hostile and abusive. In these relationships, the partners often abuse each other physically. The people involved become overwhelmed at any sign of affection and caring because of which they are not sure how to receive it. The partners are desperate to just have the other person around them even if they have to fight.
However, this kind of connection gives a much better feeling than being institutionalized. Because both the partners are scared to be alone, they desperately try to find a replacement the moment they get out of one relationship. This relationship turns out to be a co dependent one.
