I was the one that kicked him out. I was the one that talked to Ls. I was the one that told him that I hated him and to never come back ... Sadly, I think if I had been in the mindset that I am today at the time of BD, then I don't actually think he would have ever left and had the full on A. I think he would have stayed and wanted to work on the M. That is not easy to admit, but it's time that I do.
Blu, I'm not sure you should necessarily beat yourself up for this. There's no way to know what would've happened if you'd been less harsh and he stayed. He might have still gone to the full A eventually, and y'all might not have made it to piecing at all. Don't get me wrong, it's a good thing to look back and learn from mistakes, but I don't think this should count as a major regret for you.
