Good article and I guess sadly I can identify with it.
My ex was the type that always needed a confirmation of togetherness...(not sure how to word that).
If we were out together I should have been holding his hand, if we were sitting in the room together I should have been sitting right next to him. I loved him very much, but I just don't have that "constant on" feature...honestly it was stressful being with someone who did.
I need "alone time"....it's time where I can relax and not have to worry about what I say or do and how it will affect someone else. Out of all my relationships over the years that has always been a problem...if I needed time alone I either "didn't care" or I was "seeing someone else"...which was far from the case. The more I withdrew...needing to recharge...the more the other person usually pushed for more until things usually just broke down.
I think men may have it easier in that aspect (not all do though)...they are often encouaraged to go fishing, go hunting, go ride the quad...etc...take a break..a woman is often looked at "you need to be alone?...whatever the heck for?"

How or why do you think people expect this from women? We're humans too. It's a puzzle.
