OK, I'm probably the last person who should be giving you advice, but your use of the word "signaled" caught my eye. What do you mean when you say you "signaled" to GP?
If he showed up today like nothing happened then maybe he didn't get your signal? Or maybe he sort of got it but isn't taking it seriously? What if you just told him honestly that the R isn't working for you and you don't want to see him any more?
