<human>: Hi Reddit,

About 9 months ago my ex-girlfriend cheated on me while I was enjoying my summer vacation. Before I went on my 3 week vacation there was some stuff going on between her and another guy. I said something of it because it didn't feel right. We had some arguements about it, but my gut said I could not trust her so I asked her if I could. To reassure myself I could trust her. She, ofcourse maybe, said I could trust her. So I went on my vacation quite relieved. 

I forgot to tell, after my vacation on my own I had made plans to visit a city nearby for a few days. 

During my vacation I had some contact with her and she told me he had made his move. She told me he tried to kiss her at a party. She told she denied him. So I felt quite good but also quite furious about this guy. This was a week before I returned home. 

Here's the thing. The day I got back I picked her up from the bus station nearby and she asked me if we could stop before we arrived at my house. Then she told me that she cheated on me, not by kissing but she had sex with that guy. I was speechless. I didn't know how to react, the mad response came after we even went on that short trip when she wanted to break up with me. Then I felt furious. 

This experience, that week after she told me she cheated still bothers me sometime. Then it just slips into my mind and I feel disappointed. I have had a relationship between her and now, it's just.. It still bothers me. Some people here who had similar experiences? What did you do to get fully over it?

Oh and if you're wondering if she ever said sorry or apologized to me, she sent me a textmessage 2 moths after. Very short, to tell me she was sorry. I didn't respond.

Give me the gist of the text in a nutshell
