Kis, I don't feel you're incorrect in your thinking. You're right. Girls should know better. They should know their worth and know that they deserve far more than this. They should have the common sense to see the blaring red lights and sirens going, "Hey, something isn't right here!" They shouldn't assist men in perpetuating cycles of abuse, because of course it's never an isolated incident when reaching that magnitude, whether it be physical, mental, or otherwise. I understand you've experienced life long enough to know the lack of resources for women back before compared to the incredible support groups women have now, and I can definitely appreciate that.
My addressing of this has been heavily on the original poster, as people who haven't experienced said situations tend to be far more critical in their thinking and often say things like, "Well they should do this...", without realizing how difficult that decision may be for the person who is actually involved, then dismissing the difficulty as the easiest decision ever.
Saeria, Jo, and you have said that it was difficult. Love, outside influences like family, the church, and everyone in the world who feels like they have a stake in your life and believe they know what is best for you are going to give you a piece of their mind, whether you wanted that piece or not.
So in that, I acknowledge she shouldn't stay, but I also have an active imagination. And so I wonder, if she's staying, what is her reasoning? She may love him. She may feel guilty...in the report she was also aggressive to him. She may be blaming herself because she thinks she partially allowed to get it to the point it was and that it wouldn't have happened otherwise. I imagine his family telling her, "He's the sweetest guy ever. We've NEVER known him to do this. You see his dog died today and...". People in her life may be willing to break down what she knows to be true, and suddenly her truth seems hazy and cloudy. I don't think it's right or should happen, but it's probably a strong possibility.
I hope you don't stop posting here. I always enjoy reading your point of view. I don't mean to dismiss yours as if it doesn't have merit, so I do apologize if this is how I've been coming off. But I would like it if you continued here with your thoughts, because in this case you have even experienced it yourself.
