A L will know what you can and can't do about the guns. I laughed a bit when you said she said you two would need to sell everything to split, even when I doubt that would be needed. I'm sure that would mess up many of her items also and shes not even thinking about that. We talked about these bully tactics in other threads. Our W's know us intimately and know what we fear. They know what buttons to push to make us jump and go along with what they want. Usually it's all bs and they know it but are otherwise powerless to get exactly what they want. Telling you that you don't need a L and if you don't agree with her terms you will need to sell all your items, even some family guns? Yeah, she's playing you right there.
I can see both of you have some comments that you will remember. It will fuel your anger at what's happening and you will remember them. "I'm a single woman with no attachments to anyone and can do anything I want" am while talking to OM, and "the decision to divorce you was the easiest decision I ever had to make" are Teo of the ones that are burned into my memory from early in the year. You guys don't know who your W's are and the way they act is making you sick, angry. Your entering a rough place where that anger will want to consume you and you will want to lash out at them. You will need to keep controlling your actions and resist that anger. Resist being cold and a dick to them. I understand how easy it will be but understand it won't help anything and it won't make you feel better for more than a moment.
I've been through the repulsed phases with W where I wanted to hate her. Where I didn't want her in my life at all, where I wanted to see her suffer for everything she's done. Even where o couldn't imagine ever being with her again. Just remember feelings change all the time and it's very likely you may feel different in another month or two or six so continue to act like the men you want to be regardless of what they are doing.
Accept what is, let go of what was, and have faith in what will be
