Would you ever apologize to an ex?

Here lately, I have been taking the time out to getting a better understanding of myself and just trying to move forward with life and I have come to rethink some things that may have happened in my past and not that it was a regret but I also think about my exand how everything kind of played out it ended on a amicable note but I think I felt like I needed to explain myself further, and I definitely could not put things into words at the time

Now talking it out with a friend, I realize that maybe I have hidden feelings for this person still and I cannot do anything about it
