Did I make the right decision?

Hello everyone..here it goes
I just broke up my 3 yrs relationship because when I invited my boyfriend to the law school graduation ceremony (very important here in my country, it is at the Supreme Court) he told me he wouldn’t go because it was too early in the morning (7:30 am), he would be very tired to go to work to open his restaurant at 11. am and he would never ever do “such” a thing for anyone. I felt very very dissapointed and disrespected I cried a lot, he apologized later, and went anyway. The thing is that, I just couldn´t get over it, it made me think that he is just a very selfish person, that never valued my efforts and the love I gave him, because I’ve been there for him whenever he has needed me to, I would wake up at 3 am to see him if he called me in need… I started to imagine things like being married and having kids and that he just wouldnt get up to check on the baby because it “would be too early”.. and so on I kept remembering things that happened during the relationship, like him saying to me on several ocasions “If you ever get fat I’m going to leave you” and shit like that… of course he and I had good times together,and when he’s not thinking about himself he can be the most sweet man ever, and so I miss him right now .. anyway.. did I overreacted?? should I take him back since he is so sorry?? I told him we needed to break up or at least take some time apart because I was just very angry and hurt.
