<human>: Hello people from r/relationship. The last few days I've been feeling down because something that I discovered about my GF.

To put in context, around 1 year ago I accepted a job that required me to move from where I lived, to a really small village. At that time I was dating a girl for 2 years and tried to maintain a long term relationship that lasted 2 months before we decided to break up because we didn't feel like it was going to work. 

Two month after I started working in this new place, a coworker arrived. We became very close really fast, and within two months we started dating and is now my GF.

I admit I'm and insecure person, so when my new girlfriend started talking me about her previous partners, it wasn't the most amusing conversation, but I know that is my problem and I try to work constantly on it, and I know I have no right to judge or say something about what she did before she was with me. Nevertheless, for my piece of mind, I had to ask if she had any partner on the two months she was there, if she had said yes I would just shrug it off and be happy with her after, but she said no, and that to her it was important  I knew it, because of what I could think of her, not being slutty and stuff.

The problem is around a month ago I found out, not from her, that she kissed a guy a few weeks before we started dating. No big deal, maybe it wasn't anything important to her, so not worth mentioning. And last week I found out that she slept once with this guy. This guy was there on work too, and left the village around two months after we started dating. 

I firmly believe she has been faithful to me since we started dating, I'm not doubting that. However I'm feeling down, and don't know what to do or say to her about this subject, the fact that she lied to me is hurting me.

Can you give me the gist of the text in a nutshell?
<bot>: GF told me she hadn't had any partners since she arrived to our village before we started dating. Now I discover she slept with a guy and lied to me.
