Went to the gym today, and saw my ex's car outside. At this point I was pretty jittery, hoping to run into her. I ended up seeing her walk out of the gym but she didn't see me. All that time, I was in my head, telling myself that seeking her out to acknowledge her is pathetic BP behaviour. But still, I ended up walking a bit faster and ran into her just as she was heading out.

I want to prevent this wholeheartedly. If you've ever gone through something like this, how have you convinced yourself to maintain RP behaviour and not act on such an impulse? I really feel like shit now for doing what I did.
