Welcome, MTK. I know this is all very scary for you right now, but we have a saying around here, "Nothing changes, if nothing changes." When it comes to living with an active addict, waiting around for them to change is rarely a winning proposition.
But that does not mean you have to leave right now or that anyone here will look down on your choice to stay indefinitely. It does mean, however, that if you want some relief from your situation, YOU may have to step outside your comfort zone a bit.
The good news is, you've already started by posting here. Even if you are not ready for Al-Anon, you can begin to educate yourself about the nature of addiction, and you can do that by reading as many threads here as you can and taking the book recommendations above. Alcoholism can have resounding effects on all who love and live with the addiction, and we all need as much knowledge and support to heal from it as we can get.
