Okay i need some advice here. So basically, my girlfriend and I have been going out for a little over a month now, and recently she told me that before we met, she and a friend(that we both know very well) had a thing for each other and they did some things together(everything but sex). And the thing is, she told me all of this before except she told me it was with some other guy I didnt know. So basically, she lied to me, and the only reason she told me the truth is because I asked her if they had a thing for each other before we started dating. She apologized for lying to me and said thats all in her past. And i believe her. Soo my question is, how should I go about this situation? I told her I needed some time to think, so I haven't talked to her since yesterday.. What should i say to her? And I'm not really sure how I should react. All i know is that im a little upset and I find the whole thing a little disgusting. Thanks.
