It's up to you, but, i think you should not close the door on the R with C!
I'd say that those "hints" from bookeeper area sign. Like I told someone else this morning; It's not over even when the fat lady sings" So hit the darn lady with a 2 x 4 if you have to or tell her to shut up, LMAO!
Give C space and time, give her a chance to miss you. Time is on your side. I think you should go back through some of your threads; there were a lot of baby steps.
