Emotional Attachment
Firstly, some people especially ladies who are emotionally attached to the partners who maltreat them emotionally physically or otherwise they choose to remain because they are attached to them. You must have had the slogan love. People who are falling deeply in love may not have it fair living such relationships even though they have been abused. Love in this regard is the affection they have built over time.
Culture
Another reason why some people will choose to remain in toxic relationships is what I referred to as cultural perspective. In African culture, a woman is made to remain in the marriage no matter what he faces there. It is believed that her marriage is her cross and she must carry it to the latter, until death brings a separation. In recent times the African woman has been empowered by civilization and modernization to leave an abusive relationship though many women are still caught in the web of the cultural position where they are established.
Finance
In the case where one partner is financially dependent on the other he or she finds it difficult to leave an abusive relationship. For instance, a friend of mine reported how a medical doctor usually abuses her emotionally. She dictates everything that happens in the home, leaving the man vulnerable. Due to her income level the man has accepted this as fate and clinched on his wife despite the emotional abuse. In other cases most women decide to remain in toxic, even married relationships because they are dependent on their husbands for this reason they remain so as not to suffer the unknown. For them it is better to live with what is known than to pursue what is unknown.
Other Reasons Include:
Religion also plays a vital role in this discourse. For instance in the Christian religion it is believed that you can marry only once no matter what happens in the marriage you should remain praying that the partner who is toxic will repent and become friendly and capable to live with. The hope for change has made a lot of people remain in their toxic relationships. In the real sense of the matter only a very few toxic people would end up changing their attitude. Their partners may end up becoming victims which sometimes may lead to untimely death.
Low self-esteem is another factor that has made individuals who are currently in toxic relationships to remain. This category of people find it difficult to Mount up with the decision to work away. They do not have enough liver to make a drastic decision to stay away from such a relationship. They would rather suffer and smile because they do not have the capacity or self will to leave.
Fear of loneliness may be another reason why some people would not leave a toxic relationship. I can remember vividly how I remained with my one-time girlfriend who had a lot of boyfriends and myself, but I could not leave because of the many advantages I was enjoying at the moment. One of those advantages was that I had access to our money and the most and romantically she was available. The fear of who will fill the gap if I leave that relationship engulfed my being such that it took a very long time before that decision was made. I did not want to feel lonely. This is why I kept on in the relationship even though I knew that it was toxic.
Generally speaking a lot of people suffer toxic relationships but due to one reason or the other, they choose to remain. Some victims could be manipulated or under the control of another person. The feeling of guilt or due to obligation under which such a relationship was built could be difficult to work away.
I agree with the financial aspect of it. People tend to endure because of their financial trouble and they think staying can enable them to get financial stability.
No reason is good enough to remain in a toxic relationship. Any victim should move out of any such toxic relationship else, be ready to pay the ultimate prize.
That fear of being alone is always relatable. Placing your self esteem before your relationship is a good solution in order to keep your relationship healthy
It's quite unfortunate that many people do not have the tenacity to quit a toxic relationship.
