Stupid The Magnus Archives Headcanon #9:
Lonelyeyes edition:
They get divorced so much because they care about each other. Hear me out.
Peter NEEDS to be alone. Being involved, it’s draining, it’s antithetical to what he is. But he does truly care for Elias.
Elias loves paperwork. Any properly drafted paperwork can cause anyone proper amounts of paranoia. Writing up the divorce papers and adding (useless) stipulations is exciting.
Elias knows Peter needs to be alone at times, and Peter knows how much Elias loves those useless contracts.
So when Elias Knows Peter is drained past comfort he finds something small to get divorced over. To them that is how they say I love you. You’ll never hear them say the words but they know it.
