Sorry I haven't been around much - h problems! I'll be away for a while now.
Just a quick note to say, that reducing negative feelings is not appeasement. It is not rising to or engaging in the argument, two quite separate things - therfore reinforcing her negative feelings. You are still quite able to be firm and set boundaries whilst doing this.
Also, Michelle says that you should try things for at least two weeks before deciding something does not work. As I see it, the blow ups were getting less and less. Anyway, Puppy is right that you should do what you think is right. Keep in mind that you can't control your wife and probably not a lot is going to work at this early stage. You need to decide whether you are in this for the long haul - even then there are no promises but DBing is a pretty amazing tool.
You have a tendency to be negative, keep up your PMA it will be invaluable to you. Good luck with the job contracts.
