First off i am 18 years of age and a male. Yesterday was a very difficult day for me. My girlfriend(which is 19, and we have been together for 6 months and live together) and I came home after i got out of school. She said she had to tell me something and that ended up being that she cheated on me with her best "guy" friend that she has known since she was like 3 years old. She said it was only a kiss. I know who the guy is and would have never thought he'd do something like that. Maybe it was an act of jealousy? We talked most of the night last night and we really want to make it work out. Shes going to go stay at her moms house for a while and i'm still in a world of hurt. She also feels really bad for what she did..but how do you react to something like this? I love this girl with all my heart..but i'm just not sure how to feel right now.
