Boundaries are for you. There is no unreasonable - there is just your own preference, your own decision on how you want to live and what you're willing to put up with. It is not for anyone else to pass judgment on you - boundaries are very personal things, and everyone's different.
You gotta do what you gotta do. Me, I am really done with lying and deception in particular, and also with people who are simply unable to say "no" to alcohol. Sounds like you are too. Life's too d@mned short.
Take care of yourself now
