To Lightbrite and many other posters here.
Divorce is a complicated sugya, since intimate relationships are complex. Of course there are cases where one spouse is so difficult to deal with that it may be almost impossible to live with. However, that being said, the fact still remains that most marriages are workable through the proper attitude and the right communication skills.
Since there are cases where divorce may be warranted, therefore any spouse seeking divorce can easily (and will) justify himself/herself that he/she is from that minority, and will also portray his/her spouse as being from that minority, whether true or not.
The general public has also become more sympathetic to divorce, and many therapists easily encourage it (with the approval of rabbanim who merely rely on the therapists), so therefore it has become socially and psychologically easier to divorce. So rather than going the harder route of putting a sincere effort to work things out, we are seeing many people with workable marriages opt for divorce, which explains the dramatic increase of divorces in our community.
