<human>: My (20 f) now ex (20m) that I dated for about a year and a half broke up today. The topic we had fights about were fixable but there was one thing that was bad. He said that the two of us can't have a good conversation together because he doesn't know what to talk about with me. He kept saying I love music but he loves football and is indifferent about music. I am same with football. Then he asked me what he wants me to talk about to which I said I can't just tell him to talk about such and such topics. We kept discussing and finally he said this will be a problem and that he feels like "we both will be happy with someone else". At the end, before I left, he also said that some years from now he will realize that he made the biggest mistake. I didn't say anything because before he kept saying we'll be happier with someone else. It hurt to stay there longer. I also told him never to contact me again and blocked him from everything. I really loved him. 

We're in college and have classes together and I dont know how to face him or other friends in my class who loved talking about us and some who considered us "that couple". He said he loved every thing about me but he just can't see us together in the long run if he can't talk to me about things.

I am just kind of lost. I have friends I can hang out with but I just want to stay alone and think about what could've been fixed but I dont know if he feels the same way. How do I feel better?  Reddit, please give me some of your thoughts and tell me if I did the right thing. Make me feel certain that it was for the best.

Can you provide a brief overview of the text?
<bot>: me and my now ex of a year and a half broke up today. Issue was that he didn't know what to talk about with me anymore. I feel lonely and sad. Did I do the right thing? :(
