Isn't the analogy about a Frog in water !!
Yes, and it still doesn't work, for the reason I gave above.
I was in an abusive relationship once (emotional and psychological, not physical). I knew it was bad, but the experience was so exhausting, it took me many months to find the energy to extricate myself. It's even harder when you work with the person involved, as I did at the time.
I eventually got myself transferred to a completely different shift so I wouldn't have to see her. She came round to my place at 4am, shouting and bashing on the door for a good 15 minutes before I finally let her in, gave her a piece of my mind, and told her it was all over.
Never again.
