Newly married, overcoming stress

This is so sad. You started a marriage with many strikes against you that are extremely difficult to overcome in the best of situations. I'm sure you realize that international travel will be on hold for a long time, and visas are mostly suspended.

If you want your marriage to succeed, you will both need to control your anger. In your shoes, I would have a discussion in a calm moment about resolving to not ever raise your voices to each other and to give each other the benefit of the doubt at all times. It's important to keep calm and talk through difficulties and misunderstandings instead of getting heated up about it.

Japanese culture is so very different from American culture. I am the child of Japanese and American parents, and grew up in Japan. While it is possible to bridge the culture gap, it will take a tremendous amount of patience, thought and consideration, and above all, maturity from both of you. You are very young and that will be hard, but I recommend that you both agree to keep calm regardless of what you are feeling, because the relationship is of much higher value than a momentary emotion. Pray for each other and together, and ask for God's guidance on what to do to have a successful marriage. Praying together will deepen your bond and help in the spiritual growth of both of you.

You're both SO young, from different countries and cultures, and living thousands of miles apart. Married less than a year and already the D word has come up. I would have a serious heart-to-heart with him about how committed he is to this marriage. If you're both on the same page with wanting to see it through, I highly recommend getting into counseling (maybe online through video sessions, since you live in separate countries right now?). It sounds to me like this may have been a very impulsive, hasty thing to do (getting married so young when you aren't living in the same country). Keep it in prayer, of course, and I wish you both the best.
