I don’t really understand. It’s not something that require consensus or agreement. You don’t need to present an argument for divorce. You could present an argument for buying a house or investing into something, it would require consensus. If one person doesn’t want to be married, then they don’t. Divorce and break up do not require consensus. I think last time you separated, you had this back and forth too for months. Eventually you ended up together because he won.

This is really weird. I understand that one person might not be ok with the end of marriage but even then this back and forth isn’t warranted. It almost feels as you aren’t 100% sure yourself that’s why you allow this ongoing argument until he wins. There should not be an argument. Sure nice discussion is ok but if the other person isn’t accepting of your decision, it’s fine, but you can’t continue arguing why you want to be divorced.

It’s enough for one person to want a divorce for it to go forward. He doesn’t need to consent
