Quote: Realised that I am feeling much calmer this week because OW and her H are out of town all week. Of course, come Sunday, the tension in our house will be sky high - both NG and I have been this way before.
So what can be done differently so you don't go down that path again.
First there's, come Sunday act "as-if" there will be no tension ... at least on your part.
You have now until Sunday to come up with some 180's to make Sunday a tension-free day. How about planning something totally new and adventurous for the two of you. What would that be? Into antique hunting? Start looking for the type of decor of the new dream house. You know best what would be the most fun way to distract yourselves for the day, so how would you do to go about making it better?
