I'm sorry to hear about your situation. I know that it's hard for you. I understand how you feel when you discuss the difficulty in getting a life. It seems useless to think about that at a time when everything seems to be falling apart. My H and I separated (his choice) on 1/1/10, and I've had trouble imagining how anyone could do anything but sit and think about fixing a situation like this. You're not alone there.
Here's the hard part--you HAVE to work on getting a life and avoiding discussing your relationship. Don't give anything in the book a half-hearted attempt. You CAN do this. If you want to save your marriage, you have to keep trying Michele's methods. You will never know until you give it your all.
If you're concerned about finances, maybe you should discuss that with her when you're together WITHOUT making it seem like you're looking for affirmation or validation about you/your relationship. Discussing that one aspect without discussing the whole situation may give you some insight into how she feels AND put your mind at ease about financial concerns.
