You are WRONG...now IS the time to be alone, to regroup, to focus on you...move your office back home. Alone time will allow you to get your work done without being focused on him, when he comes and goes...right now, let the friends go...you need to catch up. Work your butt off...you will be so empowered by getting things completed.
You get your power back by accomplishing things by yourself. You don't need to be within the same building of your husband to do this...that, is what prevents you from working.
There is nothing you can say or do to control him...but you can control yourself...
My H's affair lasted 2 yrs. - mine, 1 1/2 yrs.
You need to let go - allow him the time to miss you...keep it strictly business...let him wonder what you are doing. The more you walk away from him, the more he'll be interested. You won't lose him by detaching - you'll lose him by not detach- ing...that's a fact.
You can do this..............stop fighting it.............
