Stressing a lot .

I really like my boyfriend a lot but we've only been going out for a few days and he already cheated on me . Plus he was meeting up with other girls but lying to me about it . He's really sweet and from the time he wakes up to the time he has to go home he's at my house with me . But he made up an excuse that he had to go to Walmart with his mom to go see another girl . But then I almost broke up with him and he flipped shit and was telling me I was the girl of his dreams and that I was everything he ever wanted . And I told him to leave my house and he ran down the street crying he had his tablet with him and it was smashed and his hands were all fucked up my sister was driving around with her friend and on her way home she told me he was at the end of my street flipping out and crying . So idk if he's playing me or what .. I'm just so confused as to if he cares about me or not .
