Ok I(17yrs old) love my girl friend(16yrs old) and have been going out with her for 2 years now.it was really crazy like cheating arguments also I fought for her one time but in the end we always love each other and had very amazing time together. Now my best friend(18yrs old) likes me and I like her we were so happy letting our feeling out to each other and spent a hole weekend together first we went to soccer game and had an amazing time then the next day we went to the mall and movies alone and sparks flew and something was in the air that night so her and I made out we want to be together but I still love my girlfriend I don't know what to do?
