Family expectations
Many millennials experience a lot of pressure to have children after marriage. There are biological, personal, family, religious and social pressures to start a family, and this is often the cause of arguments in millennial marriages.
This might not be as common in younger millennials but for the older ones, this is still a sensitive topic.
Shifting gender attitudes
There is also a huge gender battle happening right now. We have feminism that is continuing to change our expectations as far as dating and marrying is concerned and on the other side, there is a growing 'manosphere' community where men are becoming more vocal about their resistance to feministic ideas.
This gender war has been exacerbated by social media and a huge chunk of people who are participating are millennials. Consequently, this has affected people's willingness to get married and probably triggered couples in their marriages.
Battles on who should pay for certain bills, who should cook and who should clean are a big problem for these marriages.
Mistrust and suspicion
Social media has the power to shape how we think even in our marriages. And again, it has exposed the rot of mistrust that troubles millennial marriages.
Right now, men are being encouraged to get DNA tests to confirm if their children are truly theirs. Also, the incidents of abuse that women go through in their marriages are being exposed now that we're being educated on different forms of abuse. This is another major problem that millennial couples are dealing with.
Many millennial men are also suffering physical and emotional abuse from their toxic wives leading to breakdown in these marriages.
Mental health challenges
Millennials are also a generation struggling with mental illnesses. There is a lot of unhealed childhood trauma, financial stress and other challenges contributing to this problem.
These issues have sneaked into their marriages, and this has exposed them to everything from communication issues to chronic depression and suicides.
