I broke up with my boyfriend but I love him

Well, I had communication problems with my boyfriend. We had a long-distance relationship. I broke up with him yesterday because he didn't talk to me and I said to him why don't you say that at the beginning of the day? We have had issues for a long time. He is working while I'm a student. And I'm 20 yo. But he is 24. And for me, this is no problem. I know he also has issues but I can't stand myself from being such selfish... I just want to talk more with him and I was ready to talk to him without being angry, sad, or selfish toward him. Everyone I talk to blame me. I have two friends, one of them has corona so I can't talk with him and the other wants to distance himself from everybody. I feel so alone. My boyfriend was my best friend and I miss that relationship so, so much. I tried talking to him today but he says that it is over. Except for the communication problem he did nothing wrong to me. I feel so guilty. Sometimes I feel like I just... That I can make nobody happy. I just want my friendship with him back nothing else... I know we need space but I'm so alone I just don't know what to do. For even one time I want to be heard and I don't want anyone to blame me anymore because it makes me sad. Because I would always stand up for my friends no matter what. I feel so stupid and so lame... I want friends, I want to be loved and I want to be understood. I know I have to do this all by myself but it's so hard... Why are people leaving me? I want to make people happy again...
