Women in our society are conditioned to believe that they must have a boyfriend or must have a husband to be a complete person. Women are also generally more apt to be romantic and want to be loved (rather than to just be someone’s sex partner). Unfortunately, some women, are so desperate to be loved that they will take any situation, that comes their way that appears to be love and hang onto it, no matter how much damage that situation, with that person is doing to them.
Women also tend (more so than men) to have the idea that they can take a bad situation and fix it. Unfortuntately, the fixing has to come from two places. First the other person, who is causing the damage (by lying, cheating, being an abuser or whatever) has to decide to fix himself, but that rarely happens. The second person that needs fixing is the woman herself, she needs to realize that she doesn’t need to stay with a person just because she loves him, that is not a good enough reason to stay with someone. If he’s not good to her or good for her, she needs to leave, but that often doesn’t happen either.
And part of the problem is that for some women, if they leave, even if it’s an abusive or ugly relationship, they would have to admit that they did something stupid or wrong by being with that person in the first place. And if they leave, they face the prospect of potentially being alone forever and never finding anyone to love them. This is especially true with women who have not had a lot of luck in the love department before. Maybe they’ve only had one relationship in their entire life, maybe they’re older and haven’t had many (or any other) relationships, maybe they are less than average in the looks department in a world where looks are apparently extremely important in attracting men. All of this, combined with society’s view about women needing a man to be complete is sometimes overwhelming.
