did I made the right decision or a mistake?

I met a guy on tinder who I myself never thought I could even be with him. Swiped right, anonymously matched with him, and started with a conversation about meeting up. He was very persistent in actually taking me out (Ryan gosling notebook moment). We ended up going out and I ended up being his girlfriend. 10 months into the relationship, I felt oddly restricted from the most important things that is leading me to my future. The guy wasn't a bad, abusive, manipulative guy. He was actully very loving and kind. But then I realized who this guy really is and ended up being a selfish workaholic. Like recently my cousin died from leukemia, I called up the guy and all he ever did was "I'm so sorry, may he Rest In Peace" and went back to work. It broke my heart that he never even once dropped everything and comforted me and supporting me in attending the funeral with me. I confronted the guy and broke up with him. He ended up crying in front of me, but I didn't. Now, that I am newly single, I sometimes do miss him, more like the special times we had during our relationship when we talked as if we were best friends. I do not want to exceed my expectations, but I don't want to loose contact either. I still care, but I don't want to repeat my past mistakes.
