I feel horrible, but I believe I did the right thing.?

I have an ex whom we dated for a almost a year 3 years ago. Through out these 3 years there have been attempts of getting back together but we never did due to the lack of trust I have towards him. In January, he finally bid me farewell, told me "See you next life time, I will always love you, take care." and I tried to stay in touch with him, but he didn't reply back ever and basically kicked me out of his life. Fast forward to now, I ran into him and he spoke to me, I just stood there for a couple of seconds, looked at him straight in the eyes, had a straight face, and walked away. I decided when he kicked me out of his life that I was done with him in my life too. I feel bad for what I did, but I believe it is the right thing to do.
