I think you seem to have had a good talk with her. However I don't see why you think she should be allowed to take the kids from their home.
You better talk to a lawyer, or at least tell her that she cannot take the kids from their home. SHE can leave if she feels like she must.
Not offering any 'resistance' is not the same as 'acting as if she is forcing a divorce'. Did you make a list of 'stuff' she wants to take? Did you discuss how she is not going to 'just take the kids' because SHE is unhappy?
What about THEM? She can stay in a separate bedroom or something, but to disrupt the kids lives because she is UNHAPPY?
Think about it. Don't be mean, but be firm. Consult a lawyer.
