I think boyfriend wants to break up

Ive been with my boyfriend for a year. We got into an argument Sunday night. I was upset because he can be over friendly with girls and I find that flirty and disrespectful. Ive loved him all this time and I felt that he started to love me too. I finally told him I love him during the argument and he said he doesnt love me. I told him its okay hes not there yet because love grows and takes time for some people. He doesnt think its okay. He told me I should go home because I kept crying. He was crying as well. I told him I wasnt leaving til we talk it out. He has a game in the morning so he fell asleep and I ended up leaving his house. I havent heard from him since. I reached out Sunday morning, Tuesday, and Wednesday night telling him we need to talk because the way we left things was confusing and Im not sure whats going on. I want to work it out, but I feel he doesnt want to. A few weeks ago he promised he wouldnt leave and he wouldnt stop trying. That sounds like love to me. Since I havent heard him, I want to show up at his house because I really need to talk to his out. Not begging him, but at least know whats going on with us and what are we going to do. Thats the only way I can reach him since he isnt answering any calls or texts. I did tell him I didnt. Want to show up unannounced but I will have to if he doesnt answer.
