My boyfriend and I have been dating for 3.5 years. We are now juniors in college but I just today found out that he kissed 2 girls on one night at his college his freshman year (while we were dating). We have been so happy and perfect ever since after this happened. We had a rough patch when this happened but ever since then we haven’t even argued and we spend the most of our time together and we are so happy. I am so conflicted on what to do because I love him and I know he loves me. This happened a long time ago and I don’t know if I should break up with him because I think cheating is so terrible… or stay with him since it was so long ago and we have grown so much since then.
