How Often Do You Think About A Girl?

If I really like her, there's probably not an hour that goes by that I don't think about her. And it doesn't matter how long I've known her.

Constantly. Not like a complete obsession, but she's always on my mind, no matter what I'm doing. I'm doing homework, and then I just start thinking about her. It's not exactly all encompassing, I can concentrate on other things, but when I'm not occupied, she's what I'm thinking about.

There's a girl I've been out with twice. Unfortunately they were short relationships at the time because she was afraid that we wouldn't be able to see each other much. She very much regrets it now, but I completely feel for her still and ever since I laid eyes on her when I met her in Austria on a ski-ing holiday. She doesn't live that far from me.
I think about her constantly. I feel as though we will be back together again soon though.

All the time any girl we like will be on our minds constantly!!

I think about this girl named Katie pretty much everyday

I think about my girlfriend all the time. Always trying to please her and keeping her happy. When she's upset at some thing or scared I am always there for her. At night I put my phone right next to the pillow, and have it as loud as possible with annoying ring tone to wake me up when she wants to text. In other words, I think about her 24/7.
