I see what you're saying, but sometimes we just outgrow relationships and move on in life and thats cool...
Are you still friends with everyone you were friends with 20 years ago?
I have many friends I grew up with and am still friends with, but even ones that I have grown apart from, they could call me TODAY with an issue, problem or grievance and I'll address it straight up.
In fact, I had a similar situations like this happen to me and one of my close homies I grew up with. Me and my man Jason went on a trip to ATL a few years back and he ended up doing some dumb shyt that ended up costing everyone some money and wasting everyone's time and when we got back home, other friends asked about the trip and I basically said we had fun but Jason kinda fukked us for a certain point. Jason was mad at me and didn't talk to me AT ALL for almost two years because he felt like "I put his business out in the streets". I didn't even know he was mad at me until his wedding was coming up and I got no original invite. As SOON as I was told he was mad at me, I called him up that hour and hashed it out with him, I felt like, man you cost us ALL money and time, I'm not mad over it, but you damn sure I'm gonna address it when asked, I paid the right to. We squared it away, but it did reach a point where things were heated, but we needed that to get past that.
C Webb ain't gonna have nothing but hate and anger in his heart until he addresses it, then he'll be like "what was I mad for all these years". My homie even admitted he was being immature and his anger was getting the best of him over it, but I get it because nobody likes to admit when they are wrong. C Webb is working through that right now.
