Speaking as the child of an alcoholic you owe it to your kids to leave!
Addicts lie - always, repeatedly, convincingly
Also, being raised in an addicts home makes it more likely your kids will develop addiction themselves or other mh issues, more likely to attain less well educationally and subsequently that affects their socio-economic status too, are more likely to marry/enter a long relationship with an addict too
Was either of your parents a compulsive personality type? An addict?
Addiction comes in many forms some of which are not yet fully acknowledged by society
Of the 3 of us, I have severe mh issues mainly ocd (mostly borne out of a compulsive need to control my environment at heart), my brother is pretty tightly wound and my sister is an addict (otc meds)
You owe it to yourself too. To live a life free of the stress this causes and not be living a life of treading on eggshells and dreading the next binge, him losing his job or even coming to serious harm as a result
The non addict parents often think the kids don't/haven't noticed and/or aren't affected trust me they do. Even very young ones modify their behaviour and sense the tension and that is unhealthy for them
They'll promise you the moon on a stick but cannot deliver.
I have a family FULL of addicts (there is much research that a genetic factor plays a part) - alcohol, drugs (street and prescription and otc), gambling, spending, exercise, work... the "substance" isn't the issue it's the behaviour that has to be recognised, acknowledged and addressed by the addict.
None of them were able to get clean/sober alone. Those that are now clean/sober had a lot of support from various avenues and agencies and have continued to accept that support for decades. I'm a firm believer that once an addict always an addict. You can be in recovery but never cured, not least because the brain chemistry and in some cases physiology are altered by the addiction.
Some have used AA, some their gps, some other addiction support and recovery programmes.
Some never tried to get clean/sober and have now passed away as a result - that's totally heartbreaking
Some occasionally try to get clean/sober alone but I've not seen that work yet.
There are 3 facts as someone who loves an addict you need to know
You didn't cause it
You can't control it
You cannot cure it
The only person who can do anything about it is the addict. And only if they genuinely want to stop - not if they're doing it to placate someone else or prove a point or even court ordered addiction treatment ime. It's not until they are ready to face it does anything change.
Alcohol is actually one of the worst because it's everywhere, it's legal, it's cheaply available and it doesn't generally kill quickly it can kill but usually fairly slowly and very painfully. It is not only the liver that is affected it's the whole body. Every system, every cell.
Some of the effects are reversible many are not. Some of the alcoholics in my family quit fairly young and then when older but not old died of alcohol induced conditions that were due to irreversible damage done when they were drinking but which didn't present until they were older. It can be sneaky like that.
You have to do what is best for you and the dc.
