I Need Help . .

So today , me and my girlfriend of 3 years broke up . We break up every other week but this time is different . She packed all her things and left her set of keys at the house. We broke up because she feels I turn her down wen it's time to go down on her , but that's not true . It was just that night I was not feeling well . Idk what to do because I love her and she doesnt want to speak or see me . Please help me .
