Popa does not know why, but thinks it is a positive development.
Divorce is better than a bad marriage. Until now, divorce was such taboo that probably many people stayed in miserable marriages that they should have left.
Also, the option of divorce is what makes working on your marriage possible. G-d created divorce for a reason. I think part of that reason is that people feel more able to deal with things when they do so willingly rather than being forced to.
