Wife wants a divorce

[VFL]

She brought up me signing the papers while i was cooking dinner. she said"i hate to bring it up because it puts you in a bad mood but will you sign the papers tonight?"

Asked her why the rush since we've been getting along so good lately.

She said she needs to let go. I told her she let go last year(she told me this a while back), why does she need a sheet of paper for her to feel like she let go? She said she just does, doesn't feel like she could start over without it. That she doesn't feel like we could get back together without time apart, being a year or whatever. I told her we could separate and I'd still move and when she was ready we could work on our relationship. she said she would need to start over completely. another wedding and everything because this marriage is dead.
I told her we could renew our vows after a while and she said she would need the whole thing over again because this is dead.

I'm wondering do i need to let her go? Its been a month and she says no change in get mind, although i feel like there is doubt I'm what she should do.
