Good for you. Yes, see a lawyer. Ensure you know your rights, and get a good/fair deal.
W is eager to push the divorce forward. Let her. You don’t need to place boulders in her way, nor pave her path in gold. Of course, improperly filled out forms won’t cut it. She’s got some work to do before you consider signing. And she might even be more generous in her present state.
Anyhow, give W lots of time and space. Go dim/dark. Go LRT. Let her feel the weight of her choices.
