Serious advice please

Ok so I got out of a 5 months relationship yesterday. My reasons to breakup with him was that he wanted me to make him my priority. We used to spend a lot of time together but I never knew him personal life. He says that he a different person around me. None of my friends like him. Cz he is different person then my friends. He doesn’t smoke he drinks occasionally and he wants me to do the same. I miss him now. He has blocked me from everywhere. Also I broke up with him Cz he was talking to someone else at back when I was crying here on phone w him. I feel like everything goes around according to his mood only. Should I try contacting him again ?
