Boy problems?

ok so ive been goin ot with this boy danny for almost 2 months now. i havent seen him since last wednesday cuz i had to stay in brooklyn cuz my gma died. so i got back today and katie told me that he is gonna brake up with me for my best friend demi. and demi wouldnt tell me who she liked these ppast few days and danny wouldnt answer my texts... should i brake up with him first and should i ever forgive demi for doing this to me cuz she knows how much i like him
