He Left & I Can't Take this...Please Help?

Okay so i was at my sisters house.. and lets just call him "bob" so bob was coming over to watch a movie with us but he got there and something made him very angry with me i wont go into detail because its long. But I asked if he could take me home and he did and in the car i tried talking to him and he just turned his music up really loud and ignored me and when i was home i turned it down and tried talking to him and we had this arguement and he said he didnt wanna be with me right now and he wanted me to get out of his car. I refused for a while but everytime i tried talking hed turn his music up. I grabbed his hands a few times and he pulled away. ( hes a good guy he was just really angry but hed never hit me ) and the last time he turned the music up really loud i got out of his car and ran into my house. he sped away and I just texted asking if he would come back. I kind of regret it because hes not replying and probably wont. Im really scared and i dont know what to do. Should I leave him alone?? Or try talking to him more because it really bothers me that he wont talk to me about things, yeah i understand that hes upset but he's not being very nice to me..So should I leave him alone tonight and maybe try tomorrow or what? Please help im so confused and i just want him to come back :(
