I don’t know that some of what you expressed is necessarily true. Very often, people think, “He must have been abusive, or a momma’s boy.” Divorce is a two way street, and there are two sides to every divorce (and sometimes three). Whenever it occurs, it is a tragedy that the two people who got married were unable to live their lives out together in harmony.
Now, to be fair, many women DO seek to be divorced for “trivial” reasons. Perhaps those reasons are not so trivial to THEM. It’s not for us to judge. Unless you live in their home with their problems and issues, it is better not to make assumptions.
There are people who think that even the Gemarah lists a so-called “trivial” reason for divorce. i.e., the wife burnt her husband’s dinner. Without understanding what is behind that Gemarah, it would sound quite petty. After all, what wife has not once in a while burnt dinner, especially if her husband did not come home on time? Obviously there is a deeper ramification to the Gemarah, than the literal reading, and likewise, there are deeper meanings to what we might assume are trivial reasons for a woman wanting a divorce. We cannot judge unless we walk in her shoes (or his).
And it is VERY unfair, but men do seem to be able to remarry with greater ease, from my observation. But then again, if there are children involved, chances are the fathers do not have fulltime custody, so they seem to be freer birds than the ex-wives.
