<human>: We recently moved in together and I noticed my gf's diary sitting on her desk. I know I shouldn't have opened it, but it was just sitting there and curiosity got the better of me. It was written before she met me, but in it contained a list of everyone she had sex with. What upset me about it is that she still keeps in touch with many of the people on the list and, furthermore, it is more than double the number she had told me, which was already quite high to begin with. I love her, but I feel as though, considering the fact that I read it, I have a trust issue and, what's worse, that issue seems verified by what is a significant misrepresentation of her past. Also, the fact that she keeps this list makes me very uncomfortable. I am afraid to talk to her about it because I do not want to lose her or ruin our trust, but maybe it is too late? Can somebody please give me some guidance?

Can you condense the text into three sentences or less?
<bot>: Due to my snooping, I discovered girlfriend keeps a hit list of former lovers and it is much larger than what she told me. Do I talk to her about it/is it reason for concern?
