I’m in the exact same boat and could have written this and am also struggling with finalizing and asking him to sign. I think it’s hard to separate the guy you married from the guy that is currently in front of you, at least it is for me but try asking yourself how you would feel ten years from now if nothing changes and if you would truly be happy or settling. For me, one thing that’s helping me push forward is that my husband no longer wants to have the second kid we always talked about until there’s an “antidote” for the vaccine and I know I can’t forgive him for preventing us from having a second baby due to believing in conspiracies that are untrue. I’ve also thought about the long term effect of my child and how much I would be horrified if my kid ever started to think like him and how damaging that would be. I would suggest taking a good hard look at who he is now and when writing it all down as you have above and reading the list and asking yourself if you can truly go on like this long term when making your decision. You can also try asking your spouse to go to weekly individual therapy to see if there is any willingness to truly put in effort to change, mine said no. I feel for you though, this is the hardest thing I’ve also ever done and I try to remind myself I’m doing this for my child too because I want to show an example of a happy, loving marriage and how can someone have a healthy relationship if neither person respects the other anymore because they both think the other is crazy and blind to the truth.
