Why did we break up?

Okay. So friday I went out to lunch with a guy friend and my boyfriend git mad. I dont understand why.. I mean he hangs out with his girlfriends.. I don’t know. Anyways we got into a huge fight. It started with, what did you dor for lunch. I said went with my friend.. He was like why do you do dumb sht like that I was like… Im sorry? Were just friends no need to be mad. He said im not gunna sit around and be hurt by u.. I said I wouldnt hurt you, he said ok.. I said you dont believe me he put I don’t know. End of conversation. Next day… I texted him wanna hang out? He said why dont you hand out with **.. I was like :( dont be like this. He said well I cant I have to babysit. I was like mmhmm. He was like yeh. I was like then we just contuned to fight.. I got to the point where I was like, im done talking to you text me back when you want to talk to me and make this relationship work. He said same to you. I said unlike you I actually wanted this to work, he said I cant tell I put im sorry im such a terrible girlfriend, he said im sorry im such a terrible biyfriend I said your not a terrible boyfriend, he put oh. End of convo. The next day I texted him.. Im sorry and I told him I was stuipd and what not and I asked if we could stop fighting.. He put ok. The next day I asked him if he wanted to go to lunch.. (we always go to lunch) he replied nah.. End of convo. I assumed it was over. The next day I went and hung out with his best friend. His best friend asked him if we were dateing he said I don’t know.. I wanted to talk to him so I told him to come over to his best friends house. He did. We didnt really talk.. I had to go somewhere that nite and his best friend said he would take me. But my boyfriend? Wanted to take me. I don’t know. He acted like we were dateing. The next day.. No texts all day from him.
