When your own self respect becomes the most important thing that is when it is time to leave a R. I think you will now recognize that tipping point more quickly and you won't be so afraid of it.
True. I think I'll recognize it long before it gets to that point. I gotta tell you these days if I get the slightest dickhead vibe off a guy my tendency is to immediately:
1) Fix my lipstick. (self-validate)
2) Start packing my suitcase. (prepare to exit if boundary is crossed)
