They almost never do the heavy lifting on the paperwork. They're too busy in fantasyland to fill out forms. Did you ever read Erica Jong's Fear of Flying? She talks about the "zipless f--k" - where you meet a stranger on the trains, you clothes fall off magically without any fumbling with zippers or buttons, and there's no consequences. WASs want the "zipless divorce" - where they don't have to fill out any paperwork, suffer no financial consequences, and can just waltz off with the affair partner.
Just file and get it done if that's to your financial advantage.
