It is not lies or a lack of loyalty that ends a relationship. It is the agonizing truth that one person feels in their heart on a daily basis. It is realizing that you are coping and not living. It is the false belief that there is a verse, quote, phrase or talk that will magically make you feel content, complete or not care. However, it doesn’t last longer than a few days, before your mind and heart goes back to what it wants. It is the moment you realize that you left without ever leaving. It is the moment you realize that fear, shame or guilt is the only thing standing in the way of the life God meant for you to live.
You can't compare men or women with mental disorders to the normal expectations of men and women in without mental orders. Your dealing with symptoms and until you understand that you will always try to find sane explanations among insane behaviors. You will always have unreachable standards and disappointments. If you want to survive in a marriage to someone that has a disorder you have to judge their actions from a place of realistic expectations in regards to that person's upbringing and diagnosis.
