I have been married to a Japanese woman for 5.5 years now. We have two kids. I am in a total zombie marriage and I cannot take it anymore. No intimacy for over two years. Nothing. Not even holding hands. I have addressed this, I have tried to talk about it, etc. I feel completely dead and trapped in this relationship. We are basically roommates with kids. Life cannot continue like this and I am cannot die never having felt closeness with another human being again. She can also be incredibly mean, verbal and yes, physical abuse, kicking, scratching and throwing stuff. The relationship with her dad is bad too. He can be so mean and judgmental. I have definitely lost a part of myself and need myself back. I never ever thought this would get so bad but I have done quite a bit of research online regarding marriages between foreign men and Japanese women and I'm glad to find out that I'm not completely alone in this. I want out and I know that there's danger that I might lose my kids but I'm not sure if it's worth it being absolutely miserable to the point where life is bleak and dark in this marriage. The things she has said against me, oh boy, your ears would fall off your heads! Also, I am ALWAYS wrong and she talks s*** especially with her father about me. I can never ever defend myself. I am just supposed to shut up, take it and say "hai!". I feel sad that this has happened to me. I have usually always been a pretty outgoing, positive, and optimistic guy but the abuse I have been experiencing the past few years have really affected me. Advice?
