If you tell someone I always wanted to apologize to your face and I missed the opportunity and they didn't respond, what does that mean?

Context: I saw them in public from a distance but I couldn't stop and say hello because I was in a hurry. Later that day I messaged them saying "I think I saw you". They said I should've stopped and said hey. I haven't spoken to them or seen them in years. We had like a major fallout and that's where the apology was needed.
