Ah...feeling lonely when with people. Interesting thought...
Perhaps an introvert? Where you like this when out together with WAW?
I ask becuz I am sometimes the same way. Out with others but not present. And sometimes prefer to be doing my own thing by myself. More now than when I was with my STBX She was the extrovert. I was the extravert/introvert...and is was tiring.
I am only guessing this is a phase of the healing process and I would also say just the mental volleyball and exhaustion you and others go thru with this entire process. And pile on top of that all the other challenges (ie mom's cancer) being thrown at you. There is only so much the brain and body can take at times before you go caveman and hide.
You will find the "thing" that snaps you back into place. I am guessing it will just take some time and unfortunately that is the great unknown. Taking a break from it all is not a bad thing. I stopped going to my IC for a bit as I just needed to stop talking about all of this. STOP!!! ah...that feels better
Take a break...breathe...and rest the mind!
