One reason a person might stay in a abusive relationship is

Lack of self worth. Meaning that the person who is in the abusive relationship feels as if they don't deserve any better than that. Or perhaps that they need the abuser because they aren't anyone without them.

Denial, maybe they feel like it isn't happening or that it is their fault for what the other person is doing.

The illusion of the abusive person making them happy. They may say "But when is really happy, our relationship is amazing." In reality, the only happiness that is present creates a high because most of the time it is negative. The emotions in the relationship are either extremely low, or extremely heightened.

The person in the abusive relationship most likely did not go into the relationship getting abused from the get-go. Usually signs are shown overtime and things start going out of control when it is almost too deep to back out. I know that people usually hold onto the person that the abuser could be. "They were nice once, they can change" It's often caused by holding onto the false image. Or the hope that they could still be person they were.

Finally, a more obvious one would be that they are either dependent on the person or scared of leaving due to their safety.

I don't know if this is what you were looking for, but I hope i helped.

This is coming from someone who has been all three sides. The friend, the abuser, and the abused.

    however, coronary heart disease , or chd, is actually a result of coronary artery disease, or cad, said edward a. fisher, m.d., ph.d., m.p.h., an american heart association volunteer who is the leon h. charney professor of cardiovascular medicine and also of the marc and ruti bell vascular biology and disease program at the nyu school of medicine.

  with coronary artery disease, plaque first grows within the walls of the coronary arteries until the blood flow to the heart’s muscle is limited. view an illustration of coronary arteries. this is also called ischemia. it may be chronic, narrowing of the coronary artery over time and limiting of the blood supply to part of the muscle. or it can be acute, resulting from a sudden rupture of a plaque and formation of a thrombus or blood clot.

    the traditional risk factors for coronary artery disease are high ldl cholesterol, low hdl cholesterol, high blood pressure, family history, diabetes, smoking, being post-menopausal for women and being older than 45 for men, according to fisher. obesity may also be a risk factor.

    “coronary artery disease begins in childhood, so that by the teenage years, there is evidence that plaques that will stay with us for life are formed in most people,” said fisher, who is former editor of the american heart association journal, atvb. “preventive measures instituted early are thought to have greater lifetime benefits. healthy lifestyles will delay the progression of cad, and there is hope that cad can be regressed before it causes chd.”

  living a healthy lifestyle that incorporates good nutrition, weight management and getting plenty of physical activity can play a big role in avoiding cad.

    “coronary artery disease is preventable,” agreed johnny lee, m.d., president of new york heart associates, and an american heart association volunteer. “typical warning signs are chest pain, shortness of breath, palpitations and even fatigue.” if you feel any of these symptoms, don’t delay — call 9-1-1.
