Don't understand, why now???? Plus what do I do??

[ct man 1969]

Wife has been coming and going as she pleases. Our daughters have been away at their aunts house, so my wife is just not coming home until after 10pm each night. I haven't tried to pursue a conversation or any contact at all. She just comes home and goes downstairs. I haven't actually physically seen her in a couple of days. I'm giving her the space she wants, but inside it just feels as if this just validates her actions as moving forward with the divorce is the right thing to do. Does this mean anything? Am I doing the right thing? This last resort technique really is the hardest thing I've ever had to do (as the book points out). But like I said, inside it just doesn't feel like I'm accomplishing anything.
