You probably have tried to make boundaries before but it is rare that people respect boundaries from someone who is intoxicated...they thought you didn't really mean it....or they thought they didn't have to respect your boundaries because you were drinking.
My family did not understand when I quit in 2005.....that I needed a lot of time to myself (I was going to meetings) and that I didn't CARE what they thought...LITERALLY I knew my LIFE was at risk.
I believe your life is at risk also....So you SHOULD be setting those boundaries sober and don't be afraid to say you are fighting for your life and you will get "back to them" when you feel better.
Use the thing everyone uses....You have to put your "oxygen" on first before you can save anyone else....Right now your oxygen is caring for YOURSELF.
Your boyfriend...if your not "feeling" him sober...tell him that....I left my husband after 22 years because I was not "feeling" him sober...And I KNEW I could not stay sober with him continuing to be my husband....
So, when I was sober 1 year...and strong enough I thought to handle life on my own....I asked him to leave....its been about 13 years since then....and although I drank again and have 50+days.....now..
Losing that relationship was a great help to me staying sober for 8 years....I broke it off after 22 years....you can break it off after 1 year....to save YOU.
Besides you quit drinking so you are CAPABLE OF ANYTHING.
