My fiance and I are currently in a long distance relationship. She moved away only 3 months ago after she quit her job and felt she couldn't stay in the area. We have seen each other every weekend since then and things have been good. However, 3 weekends ago I couldn't make the drive to see her. She just started making new friends and met a guy who she liked talking to. He said they couldn't be friends because he was attracted to her. She was curious and interested. And of course the weekend I didn't see her, she slept with this guy. She told me a week ago and we have been trying to talk things out together for a week. She really sounded like she wanted to work things out the most, but as the days went on, she had more and more questions. She asked for this week to think about things. One of my stipulations was that she remember that we are still engaged and she needs to act appropriately (even though she didn't before). This whole infidelity thing kills me but I love her enough to try to work on stuff. However I am also jealous and suspicious. She is alone in the town where this guy is. She told me she wouldn't call him but I know she called him yesterday before I left. And I am 90% sure that after she called to check in on my drive that she went over to his house. She says that the short affair was just a fantasy thing and could never work out. But she didn't live up to her end of our engagement once and I believe again. I am suppose to talk to her on Friday but with this new info I feel like I should just end it now so I don't have to suffer needlessly this week. And since I'm not 100% sure about last night, should I confront her about that first?
