To answer your question, my H stayed in the same house (guest room) from Sept. 6th until Feb.2nd, then he went to a friends house, I guess. Then after mediation in March he moved to Austin, TX with OW & quit his excellent job here in TN.
Yes, he would come in & take things while I was gone. It was things he didn't want me to see him taking out. But I was nosy & found them missing.
I take it you are not D'd?? I'm sorry I haven't had a chance to read your threads yet.
We don't have any kids either, just 2 dogs & I got custody.
