What should I do to get my ex-boyfriend's attention?

I’ve been going out with this guy for about 4 weeks its been going great and everything he likes me and I like him.so one of my friends was going to have a party she invited me and my boyfriend to go. I couldnt go cause I had a lot of stuff to do.so my boyfriend was going. my best friend was too so I told her that whatever my boyfriend did to tell me she said ok. the next day my bestfriend called me to tell me that he was going out with this other girl too. I was shocked I couldnt believe it.so I called my other best friend to tell her about it and she said to break up with him.but I said I didnt want to because I really like him and by the next day I called my boyfriend and told him that I knew about him and the girl. he said that he didnt know what happened that he just said yes to her so I just clicked on him.so by the next day one of his bestfriends called me and said that my boyfriend didnt want to go out with me nomore so I just said ok,but I still liked him and I called his bestfriend and told why did he broke up with me he said that he thought that I didnt want to go out with him .I told his bestfriend that I still wanted to go out with him.he told me that he was going to tell him what I said to see if he still wanted to go out with me he still doesnt tell me his answer but I’ll be waiting what should I do to get his attention?
