Have I made a mistake or is this what doing the right thing feels like?

I really liked this guy but we were never officially together. He knew I liked him but then he started dating someone knew so we stopped talking. A year later he calls and we get back in touch he apologized for how things ended. We made out, and things were great. We planned another date but then he canceled on me at the last minute with a text. I didn’t reply back to that text of him cancelling and we didn’t talk for months. He just called me and asked to hangout again, and I said I’m done and that I don’t want to see him.

Did I do the right thing? I feel like he just always disappoints me.I feel like the bad guy for being the one to end things when I like him. Maybe it’s new years coming up that’s making me miss him. I don’t know what to do going forward.
