For some reason some women (not all) don't like their MIL and MIL don't care for their DIL.
For some reason, a lot of men do care about their MIL and DIL.
Those reasons could be due to any of above but largely it is about men in general do not like to deal with household issues and those who do are rightly called above womanly men.
I think, women need to revisit the issue and not go in to marriage relation with any preconcieved ideas about in-laws.
Your own family and inlaws, is just a combined family and that is how it should be looked at.
i doubt any sane man who works 8-9 hours a day, and everyday has enough energy to maintain his senses rather stress about the ones who dont even concerns him much, such as his MIL.
men do have issues with their MIL when their MIL giving wrong advices to her daughter, and daughter actually following them.
When was the last time a son-in-law was told his skin is looking a little too dark, his inlaws don't like what he's wearing, he shouldn't be spending evenings out with his friends or keep going out to work or that he should hand over his money and valuables to them for 'safe keeping'? Oh yeah, never :D
