It's a good idea to stay away from R talks altogether. And the MLC comment just says to him "It's all your fault, there's something wrong with you." That never goes well. If he brings up the issue of 95% of your friends want you back together, say something like, "Hmmm, isn't that interesting."
Or it all could have been avoided by saying, "It's been good to see you, take care," and going to watch your son play.
Keep working on you.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
