Do guys always stare at their ex?

I used to with one ex, cos I was thinking "damn she's getting a gut now.... dodged a bullet there...etc" mostly day dreaming and forgetting I was staring.
I hope this doesn't apply to you tho

I'd guess he/she just hasn't moved on yet, pretty normal..

Maybe he don't want to b a ex

I did the same thing to an ex back when I was in high school. I would sneak peeks at her ass during art class while she was doing a painting. She would catch me looking at her most of the time but i didnt care. I did it because i knew i wanted her back but I was too immature at the time to just be a man and tell her what was on my mind and how I really felt. I would catch her staring at me too with a huge evil smirk on her face. We played stupid games with each other but never ended up talking about it. Of course we went our seperate ways and i am happy with my life now. But i wonder what would have happened if i just spoke my mind instead of being dumb about it. Who knows....oh well too late now.

Only if she's trying to figure how to kill you without getting caught.
