<human>: Can you provide a brief overview of the text?

We have known each other for 7 years, and have been dating for 2 months. We are long distance, and I am active duty military, she is college student working at pizza place.

Last visit (25Nov) I found a condom wrapper between her mattress and wall when she was at work. I confronted her when she got out of work and she did not lie. She cheated. I am so hurt because my last relationship of 4 years ended because of her cheating, and she knew that. She told me it was not because she wanted to, but because she mixed Xanax (2) and alcohol (5 bud light platinums)  together and she was impaired and did not say no. The worst part is she sees the dude everyday. He is a co manager with her and they close together 3 days out of the week. I took a day and told her what I needed to keep the relationship going. I talked to her two best friends who have known her for 7+ years, and they said she has never cheated and this was a first, she told them she was very sorry, and she did not want to hurt me because she likes me.

Like I said it is a long distance relationship, she thinks I am fine with it now and we talk a lot and I act like nothing is wrong. But I lose sleep over this and I am already dealing with severe depression. I don't know how to bury this hatchet. I like this girl a lot, and I know me dealing with this the way I am is only going to cause problems.

And the guy knows I know, and she told him it was a one time thing and shes with me. But I was not around and she told him at work so all I got is her word.
<bot>: Girlfriend cheated, after we were dating for 6 days with co worker. She thinks everything is fine, I am really hurting over it. I don't know how I should handle this.
