<human>: Can you give me the gist of the text in a nutshell?

Before she dated me, my gf had this crazy two month relationship with a guy that she was head over heels for but didn't like her back.  At the time, we were just friends and she told me about how hot she thought he was, how they had sex all the time, blah blah blah.  Whatever.  That's in the past.  Long story short, he broke her heart and she was a mess for a long time.  About 6 months later, we started dating.

Recently I was using firefox on her laptop and I saw her ex's facebook profile in her recent history.  Going into the history I saw that since the last time her history was cleared around when we started dating, she has visited her ex's facebook page almost 400 times, including 4 times in the past week alone (firefox lets you sort pages by view count).  To put this into perspective, this is only slightly less than she's viewed her own profile, and far and away more than anyone else's.

To be fair, after I broke up with my ex, I visited her page a lot for the first three months or so.  I think that's normal for people our age.  But it's been almost a year since they broke up, and we've been dating for 6 months.  It makes me uncomfortable that she's doing this.  Isn't it time that she stop fb stalking this guy?  How do I bring this up?
<bot>: Girlfriend visits ex's facebook profile a lot and it makes me uncomfortable.  Not sure how to approach the situation.
