Should I be friends with my ex boyfriend?

So before I dated this guy we were best friends. I have never trusted anyone more than him. So then we kind of admitted that we liked eachother, so we decided to date. The only problem was that we went to different schools. So I fell madly in love with him! And everything was great but then he broke up with me he sai d" i give up on you" and since then I can't get hm out of my mind. I still love him. So I did the usual, and texted him and got mad and cussed him out but then I apolagized a few weeks later. Anyways, we decided we would stay friedns. He is in a play and invited me to go seehim I said yes and he was happy. Now I don't know if I should go because I don't want to be friends, I want him to be my boyfriend again. Help! What should I do?!
