Kasha, if you are married, you must have a very happy marriage, and not know people who are miserable.
I b”h am very happily married but know cases of a few divorces that needed to happen. I am thankful that halacha allows divorce.
If I were in a bad marriage, I would choose agunah over living with a man I couldn’t be with. A woman can rarely demand a divorce, but a man can generally grant one.
