I'm in my 40's now, but I grew up in a house with domestic abuse. My mother didn't leave him until I was 17, so a similar situation to yours, though she left him because she met someone else and went straight from one relationship to another with no gap in between.
It is not an easy journey and I don't know if it ever will be. The anger is enormous, and the older I get, the more I understand just how badly my mother failed in her duty as a parent, how she buried her head in the sand regarding the harm being done to me, how she parentified me in order to cope with the marriage. She fucked up massively by picking a shitty man, staying with him and having more children after it became apparent just how shit he was, and now all of us has to deal with the consequences of that choice. There is a part of me that despises her for clinging to the relationship with that disgusting man and making excuses, like not being able to leave until I left school. It is hard for me to have any respect for her. She chose to stay in a relationship with him rather than protect me, time and time again, and I don't know why.
One of the biggest problems I have with my mother is that she hasn't (and refuses) to do the work needed to unpick the weird behaviours she developed in that marriage, and it's impossible for me to have a relationship with her until she does.
Honestly, @user12345678901234 you need to stop crying over the bloody dishwasher and blaming your kids for making you cry. They are not responsible for your feelings, you are. All of you are dealing with the fallout of the marriage and it is not something you will get through overnight. There will be so much to unpick. Unhealthy behaviours and dynamics that you're not even fully aware of yet. You're still in a place of making all of it about you - look at the thread title you chose.
Stop comparing your children to your ex. It doesn't help them or you. It will fuel their anger, and it will also allow you to stay in victim mode. There's comfort in a familiar role, I know that, but it is not the right thing for any of you. They are not your ex. They are young people who grew up with domestic violence who have developed unhealthy coping strategies and now need to learn some new ones and have a tough road ahead.
The main thing I think you should be doing right now is working on fixing yourself, getting your own mental health sorted, so you can be the stable adult your kids need.
