Coming Painfully Out Of Denial
Conditioned responses is what this abusive cycle is all about. This is how we've been trained. We wreak of PTSD. Our responses are defence mechanisms that have kept us alive for so long. From your post, you've stated a remarkable point. You said that: "Now I am being recorded 24 hours a day." He has realized that you've had enough, so the screws are getting tighter. They will smother us until there is nothing left to suck the air out of.
Your resolve to leave has come at the right time. The respondant to your post is correct. Although it appears that you remain in denial about your "relationship": "Knowing that he does not love me is killing me."; your thinking is becoming more rational. It may still be "Stinkin' Thinkin'" but you're coming out of the pit and seeing some light. He is becoming scared that you are finding the courage to leave, and it seems, from your words...you are!
You can either feeze in your tracks from your fear of what will become of you, or motivate youself out of the ties that bind and survive the abuse. Your post exudes motivation!
