Why does my girlfriend think I’m cheating on her!?

Can it be that she’s cheating on me its just like right out of the blue she started with accusations. We’ve been dating for 2 years I honestly don’t even have that many friends and really no friends that are females. I always talk with her everyday and night but now she would say go with your other girlfriend then hang up on me and not talk for me days up to a whole week! I call her everyday text her but she doesn’t answer me at all until some time has passed. What you think?
