<human>: I stated dating a girl at the end of January and we dated for bout 2+ months. Everything was great, the problem was that I didn't give her enough attention because I recently started a new business and worked for about 70 hours a week. She wasn't asking much of me, just to go hang out with her friends once a week, go to a salsa class and so on. Most of the time I couldn't make it because I either didn't like the activity she wanted us to participate in or I was too tired from working. She ended up leaving me and understandably so, but wanted to remain friends because according to her I was a "great person and friend."

I quickly realized that I was stubborn and a jerk and she did not deserve to be treated in a way I treated her. I spent over 2 weeks trying to get her back and eventually she called me and said she wants to work things out. I was never so happier to be given a second chance. The past week had been great, I was very happy and she told me that she is glad that she gave me a second chance because she loved spending every minute with me. I thought things were great. 

Then we got on the topic of what she was doing when we were apart the 2 weeks, I had a feeling that she was with another guy, but she denied it at first. Then she called me and said she wanted to tell me the truth and be honest with me and that there was in fact another guy, but they did not do anything sexual. Only making out and touching. I didn't think I'd care, but it hit me like a ton of bricks. On one hand I know she's not in the wrong because we were broken up and if she is in fact telling the truth (which I think she is, because she can't tell a lie) not much happened between them. On the other hand I almost feel betrayed and I'm not sure if I will be able to get over it and if it will always be in the back of my mind throughout the relationship. So at this point I'm not sure if it's best to end it.

Can you condense the text into three sentences or less?
<bot>: Girlfriend and I broke up after 3 months of dating, got back together 2 weeks later, but found out she was seeing another guy during 1 of those two weeks. No sex was involved according to her.
