My wife is extremely egoistic, narcissistic and lacks manners. Arguments between us are very common. However, my wife has epilepsy, and her parents have advised us not to stress her out, as it could trigger an attack causing her to fall down. The problem is that she doesn't consider herself truly married and does whatever she wants which makes me and my dad angry.. When I or my father try to make her understand (preach her), she threatens to call her parents, who always take her side (her father speaks very rough words with me). The situation is now like we can't utter a word to her due to pressure from her parents. I'm worried that if anything happens to her due to epilepsy attack, her parents will blame me only. This stress is also affecting my health. I am too much worried about this situation which only raising my blood pressure.
