Why indeed. There's an answer, if you're open to it.
Do people act differently after the ceremony?
Seriously-Im tired of men choosing women for their beauty or sexual prowess rather than their character, then complaining that all women are greedy, manipulative witches when her selfishness (that was apparent all along) is magnified because she no longer cares what he thinks.
A persons character reveals itself in small ways over time. No one completely changes their true self just because they got married.
But go ahead and tell me what really happens to women after marriage.
