Crying is a good thing. It releases hurt thats held in. It helps people (or at least me) think clearer afterwards.
You don't need to be a hero, you don't need to save her. You just need to be there.
It must hurt that she seems to trust her lawyer over you... but that is the message you get. My lawyer reminds me that spouse is my adversary. Her job is to make sure I'm taken care of. The lawyer can give advice, that's it.
You gave her a dose of reality, in a voice that scared her. You're human. This is a scary situation for all of you. Reacting with old behaviors is normal. Following it up with an explanation will help calm her down. After all, you'd do that with a business associate, wouldn't you?
Listen to what she says. She's telling you what SHE needs. Do that. It always works in your favor.
