whats wrong with me or him?

I don't feel like doing anything or eat anything. Am i feeling depress? Sad, or heart broken? My boyfriend haven't call me almost 2 days. I think he's cheating on me even though he says he would never do that. Is he tries to revenge me? Because I dumped him last time, and we went back together, now he haven't call or text me. I miss him a lot.
