Why is it that only girls have to go to...

Their husbands house? I know because it's a tradition going on for years, but any other reason? I hate this tradition so much because it is the girls that have to tear open their hearts and leave the home they spent their whole entire life in, and your parents and family and loved ones. Boys have it easy, forever with their mumma papa. That's not fair. Why do we girls get to endure such pain while boys don't? Don't we get enough from girl and pregnancy? Something biological and impossible to pass on to the boys?
