Yeah, I mean, I miss him… I wouldn’t say I’m not happy about it, but like, it’s hard. I mean, he’s my best friend. He’s still my best friend. But I had to, I had to change something with me,” Dahmen said.“It was more about me, it was my mentality, it was what I was doing and I needed to take ownership of what I was doing, I was not doing a good job of that. So, for a way, for me to do it as simple as just playing golf on my own for a little bit. So yeah, I love him, I miss him. I think we’ll see him out of here again soon,” he added.Joel Dahmen and Geno Bonnalie’s association lasted for over a decade.
