I read it as I didn't understand how my actions were received, how I made you feel, that was not my intentions and I let other shit going on in my life feed into my grievances of that meeting. I always had so much respect for you that I thought you could be the best replacement for me (a big compliment)

I think he could be clearer on his delivery and it's obviously somewhat new territory given the context but I felt like I read a sincere apology accompanied by personal life lessons
