<human>: Dated a girl on my course, we would always spend the lectures together and any breaks hanging out in my room, she broke it off because she said she didn't want to be in a relationship this young, because she didn't want to have to hold back because of consequences of getting really drunk with her friends and going with the night.

After we broke up I deleted her number and removed her from Facebook, but I have to see her all the time, so I can't get my mind off of her, all I want to do when I see her is go over to her and for things to be back the way they were

Can you condense the text into three sentences or less?
<bot>: GF didn't want a serious relationship so young, have to see her every day, constantly reminded of what I've lost
