This question is a powder keg waiting to explode. I’ll help light the fuse 🙂
I think that chassidim have a different view of the relationship between a man and his wife, and on marriage in general. They believe that love does not come beforehand, it only comes after a marriage, when the couple spends years together. When they first get married, they definitely don’t love each other. They probably don’t even like each other – they don’t know each other!
When I got engaged, I didn’t love my wife. She didn’t love me. We admitted it to each other. We liked each other a lot, and knew we were definitely compatible. By the time we got married, I did love her, and she loved me. That was because we spent time together during our engagement, and our relationship deepened.
A chassidish friend of mine told me of one other issue in the chassidish world. Divorce is so taboo there, that even if someone is not happy at all in their marriage, they will not get a divorce. They think they will be excluded from the community if they do. Sadly, sometimes they are right. Chassidim may have a lower divorce rate, but they don’t have a higher rate of happy marriages.
