Hi Liz,
As painful as it might be, you are doing the right thing. In a way him being this way is a blessing because the mask is off. As others have said, he can no longer "control" you and it's driving him crazy. He is obviously also a very manipulative person. I would honestly say I would have no physical contact with him at all. After a break up, going "back" to gather up additional items can be a very dangerous time. I'm not trying to be alarming, but statistically this is true and has been creepy. Stay strong and stay safe
