Marriage largely is dissolved by a no-fault divorce meaning you can get divorced for any reason without proving wrongdoing. Before no-fault divorces you had to prove fault or wrongdoing of some kind such as being beaten but even then the bar to prove fault was hard and difficult which left women (and men) in abusive relationships, loveless marriages, etc.

The republican party as a whole has been moving against no fault divorces, and this will mean some people are not able to justify a divorce if the abuse is not deemed serious enough. Jd vance has spoken against no fault divorce and has said that it enables people to change their spouse as often as they change their underwear. Which to me sounds like jd vance doesn't ever change his underwear which is kind of gross but the smaller issue here.
