You should be worried that you have so little ability to trust, that you have to snoop around her browsing history.
Maybe its time to introduce new activites with gf if worried about her losing interest
RUN LIKE HELL

Nay, she was just thinking about men again.
Get over her and go out with someone else
yup she not happy with you.
You have bigger problems than her not being in love with you!
You should be, sounds like she cheated on you :c
