Hi there,
That is really bad behaviour. I know I could definitely not stand being lied to, or tolerate bad habits like drunk driving on a regular basis! Ugh this makes me mad. It is really irresponsible. What if he drives while he is tipsy and hits someone?

However, I wouldn't argue while he is drunk or even just tipsy. I would set a boundary there and have a serious talk when he's sober. Boundaries can save you some nerves in a situation when you feel like you are lied to and maybe losing perspective. It is really important.

He is responsible for his own behaviour. You can decide if you want to put up with it and how much you can take. I am sorry, but I can understand that you are feeling bulls*****ed
