Almost everyone faces some issues and they just suppress it among themselves thinking that it's the right way, and marriage is all about adjustments.
Yes, when 2 people would want to live together, adjustments are required. But often, it's the wrong adjustments that prevails.
This has been the case not just now, but almost all the time, decades back as well.
And the 1% divorce rate is exactly because if this. No one is there to support the person in problem (female/male), and usually their family also asks them to adjust (suppress it) and move on. I mean, what would the society think?
And regarding dowry, there's no shame from the groom's side. I mean, they could beg on streets rather than troubling bride's side. And most of bride's side is no less either, they want to do it for the society.
