Queen..boundaries are for you..not him.
Having said that..I can tell you I understand what that is like. My ex used to physically prevent me from leaving the house. Nice guy that one.
Have you tried telling him..if you do this, I will leave the house/ room/ and will not engage in a conversation with you?
but when drunk does not comprehend
Provided he is not phsically preventing you from leaving the house, it wouldnt matter to me if he understood or not..once Im out the door, he gets it!
I agree with Cynay, after a few times they usually, not always..but usually get it..
