wife preparing to leave me and kids

[blue2010]

Ih think I am at a reassment point my gut says she is gonna file before the middle of jan. Besides that its pretty messed rt now. She doesn't get those emotional responses from me now I have addressed that with my IC.
I was doing the supportive role as suggested above and thought that was helping until today. Without any posotive from me she seems to withdraw more.
she is set on leaving. She has taken actions to support it.
