Anna, I think you handled that fine. You weren't mean - just reinforcing your boundary. When you think about it, how appropriate was it for your H to expect to be able to ML to his W in the middle of the night when he was drunk, given his behaviour lately? Reinforcing the boundary was primarily for you. Do you feel like ML to him on that basis?
I think he was trying to 'reclaim' you as 'his' with that move. But I would hold firm on this and he will see that he doesn't get to 'keep' you and OW. If he carries on with OW, he will feel you slipping away like sand through his fingers. You will be going out with 'friends' who may or may not be male and moving forward with your life.
Now, relax as much as you can and try & get some more sleep my friend
