Make changes for YOU. I was pretty certain my W would file very quickly too. She hasn't yet. It's been over 2 months since I found out about her A, and we've been separated almost a month now. It's a tough, slow, agonizing process, but you HAVE to detach. You have to start developing into someone she wants to be around. Right now, she doesn't want to be around you. Don't change anything about you for her, do it for you.
we have all been given the gift of time to ourselves. Use it wisely.
I just spent a nice couple of days with my W. Some of the most calm, and satisfying in months. No sex or relationship talks, just two people hanging out having fun with our daughter. I never would have imagined if you asked me a month ago if this would be possible. I thought I was headed for divorce. I might still be. I don't know what is in her head anymore. But I do know that she'd much rather be around who I am now than who I was a month ago. I've still got a long way to go. So do you. Be patient, breathe, focus, and get out and do something.
