Hi, Colors. Welcome to SR.
There is a lot of good info on this site, called stickies,
They are posted at the top of the main menu.
I recommend you reach out for support for a few things:
Your consumption of alcohol. If you can take some sober time, I urge you to do so.
We cannot think clearly about anything when we are lit up.
Your SO's consumption of alcohol. It isn't normal behavior to drink as much as he is daily. Sadly, this is his choice. You can't control it or make him stop. He has to decide to do that on his own. You can, however, change you.
Which brings me to the other concern I have.
Your checking up on your SO, accompanying him to the bathroom, etc. is not helpful, though it may seem so at first glance.
You are not his mother or his nurse.
Your situation is not a healthy one right now, even though you clearly care for this man.
I am sure others will be along to welcome you.
Keep reaching out, keep posting, and keep learning about alcohol addiction.
Peace.
