Might be an unpopular opinion, but divorce law needs some big changes. I spent over 50k fighting an ex in court as she tried to take my house and savings that predated our marriage. I don't have a problem with the no-fault part, that's fine you want out you should be able to leave, but property rights stuff and the cost of a divorce both need big changes.
This is a tough one because every divorce is different, and I don't want to turn this into a huge rant, but I'm still in this process and a woman I married only 4 years ago may take my house leaving my daughter and I without a home. She's also coming after my retirement accounts, some of which predated the marriage, and she's refusing to negotiate which has already forced me to take this to a judge for a decision. Financially, this has ruined my savings. I've maxed out credit cards fighting for my rights as a parent. Basic stuff here, I'm just talking about my right to have the kiddo 50% of the time shit like that.
I didn't do anything torid in this case she just wanted to leave, which again is fine, but she's essentially bankrupting me on the way out in a ploy to take my life savings and home. There is nothing I can do about this, it is how the process works in Colorado. Be careful before saying "I do", you're signing away a lot of your rights and property when you do that. Especially if there is a big difference in networth / socioeconomic status, consider a prenup. If he/she says no to the prenup, bail.
Prenups. Prenups should be standard for all marriages. Protects pre-marriage assets, determines how assets are split, and leaves little room for long, drawn-out divorce processes.
You can make those rational decisions when you're happy and rational, rather than when you're emotional.
